The review paper <ref name="PMID26932668"><pubmed>26932668</pubmed></ref> mentions that the mammalian heart was believed to be a post-miotic organ (an organ that is not able to undergo mitosis) but recent studies show that adult human cardiomyocytes can be replaced but a low and detectable rate but this rate is not sufficient to compensate large scale tissue loss in the heart. So different approaches have been explored recently to try to find methods to regenerate cardiac muscle, in so cardiomyocytes have been used in regenerative medicine. Here the review article briefly describes the process of how cardiomyocytes grow during embryology. The cardiomyocytes proliferate during fatal development and also after birth in the first days of postnatal life, and this enables a huge increase in cardiac growth. | |||
Here the review articles mentioned how teleosts fish can regenerate parts of their heart after injury and it is also observed in some urodele amphibians. The article mentions the fact that neonatal mice also have some ability for cardiac regeneration and here the research article by Porello et al.

The review article <ref name="PMID26932668"><pubmed>26932668</pubmed></ref> explains that since cardiac muscle regeneration is observed in neonatal mice, this capability needs to be addressed in human heart muscle in order to see if this can be used to recover human heart muscle mass and function. Interestingly the review article <ref name="PMID26932668"><pubmed>26932668</pubmed></ref> also agrees that in order to understand human heart development and function it is necessary to investigate the regulation of cardiomyocytes in different contexts and in different species. |

Review of a publication on human fertilisation
<pubmed>26995337</pubmed>
Write a short summary of the papers main findings
During development, all vertebrate embryos pass through the somite stage, which is defined as any developmental stage between the formation of the first and last pairs of somites in embryos (Gilbert, 2003; Mu€ller and O’Rahilly, 2003). The somite stages can vary and is not very accurate, but correspond to CS9-CS13 and occur approximately during the third and fourth weeks after fertilization of the ovum.
This study uses 37 human embryos (already fertilized) that were obtained when pregnancy was terminated during the first trimester due to socioecomomic reasons and form part of the Kyoto Collection in Japan. These embryos are classified following the Carnegie Stage (CS) 11-CS13 which is approximately 28-33 days after fertilization. These embryos were selected due to their good conditions, they were undamaged, and then were measured and examined using the criteria provided by O’Rahilly and Mueller (1987).
The embryos were then subjected to histological serial sectioning. The historical sections were scanned digitally and the morphology and the following primordia were histologically observed: the epithelium and mesenchyme of thyroid, the epithelium around the respiratory primordium region, omental bursa, ventral pancreas, and liver parenchyma. The morphology that was observed in the 2D histological slides was reconstructed in 3D. With the 3D reconstructions, the authors were able to create a precise timeline of the differentiation events that occur during this developmental time and provided key insights into these developmental processes. Using 3D reconstructions the authors were also able to observe the precise mechanisms involved during the digestive tract development during the particular somite stages. For example with the digestive tract and derived primordial, the authors were able to observe the morphology and position of the tract within the body and construct a precise time line during which development occurs. This differs from previous morphometrical studies (e.g. O’Rahilly and Mu€ller, 1984b; Otani et al., 2008) which showed that the size and proportion of the digestive tract and organ primordial varied considerably among embryos at the same stage.
Mark Hill 18 August 2016 - You have added the citation correctly and written a good brief summary of the article findings. The problem is the paper does not relate to fertilisation, that was the topic for this exercise.

Identify a known genetic mutation that is associated with cleft lip or palate.
MSX1 also known as the muscle segment homeobox (MSX1) gene plays a crucial role in epithelial-mesenchymal tissue interactions in craniofacial development
Identify a recent research article on this gene.
PMID 27259221 This recent research article by Paradowska-Stolarz [1] gives a small introduction on cleft palate deformities. The author states that cleft deformities are the most common facial malformations and observed in 10% of facial deformities. The cleft lip and/or palate is served in 1:700 live births. But we the reader do not know if this is a world wide phenomenon or occurs only in Poland. Males are two to three times more likely to have Clefts in the lip, alveolar bone and palate while in females isolated cleft of the palate is more frequent. Facial clefts are formed within 5 to 12 weeks during fetal development. It is still not known what is the full ethology of the cleft lip and/or palate however there is a large genetic factor that contributes to this deformity and there are a number of genes that are known to be involved in the palate formation. The author also states that there also may be a environmental trigger that also causes these facial malformations. The author states that 20% of cleft palate malformations are caused by the following genes: genes encoding signalling molecules (Bmp2, Bmp4, Bmp7, Shh, Wnt5a, Smad 2-4), growth factors (Egf, Egfr, Fgf1, Fgf2, Fgf8, Tgfα, Tgfβ1-3) and their receptors (Fgfr1, Fgfr2), transcription factors (Pax9, Tbx22, Msx1, Tbx1, Ap2α, Blx1-6, Lhx6, Gli 2-3, Hoxa2, Irf6, Pitx1, Pitx2, Prx1), cellular adhesion molecules (Pvrl1, cadherin E, connexin 43), and extra- cellular matrix ( bronexin, Col 1A2, Col2A1, Col11A1 Mmp2, Mmp3, Mmp9, Mmp13, Timp1-3) [46,49]. As well as these MSX1 and TGFβ3 genes are found to be the genes more strongly related to cleft palate anomalies.
Mark Hill 17 October 2016 - MSX1 is a known cleft factor and you summary is useful. I do have a slight problem with the paper you have selected as this is a REVIEW not a RESEARCH ARTICLE. It also looks like you have copy-n-pasted some of the text as shown by the original numbered referencing (46,49). | Assessment 4.5/5 |

Duchenne muscular dystrophy
What is/are the dystrophin mutation(s)?
What is the function of dystrophin?
What other tissues/organs are affected by this disorder?
What therapies exist for DMD?
What animal models are available for muscular dystrophy?' PMID 27594988
Duchenne muscular dystrophy (DMD) is a recessive inherited muscular dystrophy that is caused by mutations in the gene that encodes dystrophin on the x chromosome. Dystrophin is a protein which is needed to keep muscle fiber integrity. This dystrophy is caused by mutations in the gene encoding dystrophin, a protein required for muscle fiber integrity. The DMD gene is expressed mainly in skeletal and cardiac muscle [1] . Many approaches have been tested from traditional gene addition to newer approaches which are based on cell manipulations at either gene transcription level, mRNA processing or at translation levels. Currently there are no efficient treatments to treat DMD.
Who is affected by DMD
DMD affects approximately 1 in 3500 live male births throughout the world. Due to the way that it is inherited, DMD affects mostly boys, but occasionally girls are affected. It is inherited as an x-linked disease that is characterized by a rapidly progressive muscle weakness.
DMD affects all ethnicities, nationalities and socioeconomic groups, although it occurs almost exclusively in males. Children with DMD show early signs of muscle weakness and begin walking relatively late in childhood. They develop a waddling gait and have difficulty in climbing stairs. Their muscles show a false or pseudo-hypertrophy, most notably in the calf muscles, where the muscles appear large but are actually replaced by fat or fibrous tissue.
Becker muscular dystrophy (BMD) results from mutations in the same gene as DMD but follows a milder clinical course, with later development of weakness and loss of function.
Medical Treatment of DMD The most advanced treatments include therapeutic treatments.Steroid treatment (also called glucocorticoids or corticosteroids) has been proven to slow the loss of muscle function and therefore temporarily prolong a boy’s mobility. On average boys taking steroids are able to walk for three years longer and the onset of breathing and heart problems and curvature of the spine may also be delayed. Since steroid treatment was introduced more than 20 years ago the life expectancy of individuals with DMD has increased considerably, but it is not known if this is due to the steroids or the introduction of other measures to manage the condition such as ventilation.
Mouse models for DMD
The mouse model is mdx mouse. A dystrophin deficient mutant was first described in 1984 as a naturally occuring deficient mutant and was described in a colony of C57BL/10 mice (C57BL/10ScSnJ) and has since been referred to as the “mdx-mouse”.
How is Duchenne diagnosed?
Duchenne is diagnosed in boys between the ages of 3 and 7. Parents noticed that their son is not at the same stage physcially as their peers and behind in developmental milestones. Young boys may appear to be clumsy and will often fall down during regular activity. Climbing stairs, running, and rising up from the floor become very difficult.
There is an online interactive tool that can help parents detect motor development delays - http://motordelay.aap.org/
Once Duchenne is suspected from the symptoms, there is a range of tests that can be done by a doctor to reach a diagnosis, which are listed below.
Creatine Kinase
The muscles contain an enzyme called creatine kinase (CK), and when muscles are damaged, this enzyme spills out into the bloodstream. Measuring CK levels in the blood verifies that there has been muscle damage, but does not give a definite diagnosis.
DNA testing
DNA is obtained from a blood sample and scientists are able to examine the dystrophin gene to find out exactly where the mutation has occurred.
Muscle biopsy
If DNA testing does not give a clear diagnosis a muscle biopsy may be needed. A surgeon removes a small sample of muscle and it is examined under a microscope to see if dystrophin protein is present.

Lab 9 Assessment
Peer Assessment: Project 1: WnT Signaling Pathway in skin of fetus
1. The key points relating to the topic are clearly described
There are headings for key points but the information for these key points has not been added so far.
2.The choice of content, headings and sub-headings, diagrams, tables, graphs show a good understanding of the topic area.
The WnT Signaling pathway wiki does have a list of contents, which demonstrate that the topic is divided into different section. However it is clear some thought has gone into this. However this is not finished, there are not tables, diagrams, graphs and a lot of work is needed. There are sub headings but there is no clear concise information under these headings. There is no introduction on what the topic is about and this makes the reader a little confused. There are a lot of parts missing and not filled out.
3. Content correctly cited.
The content is not cited correctly. There is a reference section but there are no publications that have been cited listed.
4. The wiki has an element of teaching at a peer level using the student's own innovative diagrams, tables or figures and/or using interesting examples or explanations
There are no graphs, diagrams or tables and these clearly will help the reader have a better understanding of what the wiki is about. There does not seem to be any examples or explanations that show the students own innovation.
5. Evidence of significant research relating to basic and applied sciences that goes beyond the formal teaching activities.
This is somewhat evident but there is not enough clear information and it makes it difficult for the reader to follow the topic.
6.Relates the topic and content of the Wiki entry to learning aims of embryology.
There is a section on foetus skin formation and this will be interesting to read however it is still not finished. Figures and diagrams would aid a lot to visualize this section.
7. Clearly reflects on editing/feedback from group peers and articulates how the Wiki could be improved (or not) based on peer comments/feedback. Demonstrates an ability to review own work when criticised in an open edited wiki format. Reflects on what was learned from the process of editing a peer's wiki.
Each section has been divided amongst the group but it seems that the members of the group have not really communicated or finished their own sections. This is not clear at all. The Wiki has a lot of room for improvement, the group needs to meet and decide who will do which section, the participants of the group need to find review publications and summarise this information for each section. Also it is a good idea to see how these projects were edited in the previous years and this will help with the layout.
8. Evaluates own performance and that of group peers to give a rounded summary of this wiki process in terms of group effort and achievement.
This is not demonstrated and it seems that the key areas have not yet been researched adequately. There is still a lot of information missing and the overall flow of this wiki is muddled.
9. The content of the wiki should demonstrate to the reader that your group has researched adequately on this topic and covered the key areas necessary to inform your peers in their learning.
The key areas on this wiki have been set up but there is no clear and adequate information that is correctly cited at all. It is a very poor effort thus far in terms of group research.
10. Develops and edits the wiki entries in accordance with the above guidelines.
This still has not been achieved at all. There is no editing and it seems the group has put little effort in this project.
Peer Assessment: Project 2: Notch signalling pathway
1. The key points relating to the topic are clearly described.
There are headings for key points and the information for these key points has clearly described. This information is laid out in a clear way beginning with an introduction, historical aspect of the topic and continues to more specific information (e.g. animal models) related to the overall topic.
2.The choice of content, headings and sub-headings, diagrams, tables, graphs show a good understanding of the topic area.
The Notch singalling pathway has a very clear contents list. This demonstrates that a lot of thought and research has gone into the topic. There are two figures which are very neat and well set out. These are referenced. There is one table which described the historical aspect of this topic and this is very clear and beneficial as it summerises a lot of information in a clear manner.
3. Content correctly cited.
The content is cited correctly. If the refernces are used more than twice this has been cited in following the Wiki guidelines and the reference is not repeated in the list.
4. The wiki has an element of teaching at a peer level using the student's own innovative diagrams, tables or figures and/or using interesting examples or explanations.
This wiki does have an element of teaching: It is clearly laid out, it is easy to read and the information is set up in a correct manner with a general overview, historical aspects and then more precise information is given. There is some interesting examples given which describes abnormalities in this pathway.
5. Evidence of significant research relating to basic and applied sciences that goes beyond the formal teaching activities.
This is very much evident. There is evidence that research has been undertaken as the topic has been divided into sub topics and there is a lot of interesting clear information to educate the reader.
6.Relates the topic and content of the Wiki entry to learning aims of embryology.
Yes the topic does related to the learning aims of embryology and how Notch signalling pathway is involved in embryonic organ development through the regulation of cell-cell signalling
7. Clearly reflects on editing/feedback from group peers and articulates how the Wiki could be improved (or not) based on peer comments/feedback. Demonstrates an ability to review own work when criticised in an open edited wiki format. Reflects on what was learned from the process of editing a peer's wiki.
This is still not as evident as there is no comments or feedback observed. There are still some sections that have information missing and perhaps comment or feedback could have been given here to ensure that the students fill in this missing information or remove the subheadings all together.
8. Evaluates own performance and that of group peers to give a rounded summary of this wiki process in terms of group effort and achievement.
The way this Wiki is laid out clearly demonstrates that there has been some feedback and communication between the group. It seems that each member of the group did write a section, yet the sections do come together and do not seem out of place. However there are sections with information missing and this needs to be addressed.
9. The content of the wiki should demonstrate to the reader that your group has researched adequately on this topic and covered the key areas necessary to inform your peers in their learning.
Yes the Wiki content does demonstrate that the group has researched adqueately in this area.
10. Develops and edits the wiki entries in accordance with the above guidelines.
This has been achieved. This wiki entry does seem to be in accordance with the guidelines provided.
Peer Assessment: Project 3: Fibroblast Growth Factor Receptor (FGFR) Pathway
1. The key points relating to the topic are clearly described.
The key points related to the topic are clearly described however the introduction is a little limited and further information is needed with examples.
2.The choice of content, headings and sub-headings, diagrams, tables, graphs show a good understanding of the topic area.
The fibroblast growth factor receptor pathway wiki does overall seem to have a very extensive list of contents, which demonstrate that the topic is divided into clear interesting sections. This wiki has a good use of a table to demonstrate history (be it small) and subtypes of FGFR pathways. In the history section it is not clear if they first discovered FGFR in human pituitary or pig or mouse. Please be more explicit. The history table does not seem to be finished as from 1999 to present there is no information at all added. Also there is no reference to the History information and this needs to be referenced.
3. Content correctly cited.
The content is cited correctly. However as mentioned there are some sections which are not referenced at all: History, Bone Development (there is a large paragraph which says a lot of what is known but it is not referenced. Some of the references are repeated in the reference list: see below in wiki guidelines.
4. The wiki has an element of teaching at a peer level using the student's own innovative diagrams, tables or figures and/or using interesting examples or explanations.
There 2 small tables and two diagrams which are educational. I am very impressed that one of the members of the group re drew the first diagram. It is quite artistic but it is a bit confusing as to what each abbreviation in the figure means. If this sort of figure is added I think that some abbreviations or an explanation in the text needs to be added to allow the reader to understand what is actually happening . If not it looks like a figure with some sort of pathway but not very clear as to what It represents.
5. Evidence of significant research relating to basic and applied sciences that goes beyond the formal teaching activities.
This is evident that the students have done a lot of research in this topic.
6.Relates the topic and content of the Wiki entry to learning aims of embryology.
Yes there are some headings which relate to the learning aims of embryology such as limb bud formation and bone formation. But there are some sections which are not finished at all Kidney development, External Genitalia development, Inner Ear Development and Animal Models.
7. Clearly reflects on editing/feedback from group peers and articulates how the Wiki could be improved (or not) based on peer comments/feedback. Demonstrates an ability to review own work when criticised in an open edited wiki format. Reflects on what was learned from the process of editing a peer's wiki.
It does seem that that the members of the group have had some communication and worked together well. It does seem that they have learnt to edit a wiki, making a online quiz, making tables, adding figures and content. Well done!
8. Evaluates own performance and that of group peers to give a rounded summary of this wiki process in terms of group effort and achievement.
This is a very interesting and well-researched wiki. There is still information lacking and more figures are needed as well as explanations for the figures. It is clear that a lot of effort has been carried out with the quiz, the figure that was re drawn from a publication.
9. The content of the wiki should demonstrate to the reader that your group has researched adequately on this topic and covered the key areas necessary to inform your peers in their learning.
The key areas on this wiki have been researched adequately. There is still information missing.
10. Develops and edits the wiki entries in accordance with the above guidelines.
Yes this wiki is in accordance with the guidelines. In terms of the reference list, some references have been re cited and added as new references, please see editing guidelines to avoid this- as so the reference is only listed once in the reference list and not multiple times.
Peer Assessment: Project 4: Hedgehog signalling pathway
1. The key points relating to the topic are clearly described.
The key points related to the topic are clearly described however the introduction is a little limited , as there is no information just a figure without any text related to the figure.
2.The choice of content, headings and sub-headings, diagrams, tables, graphs show a good understanding of the topic area.
This wiki does seem to have a very extensive list of contents, which demonstrate that the topic is divided into clear interesting sections. However it is not finished and there are empty headings with no text underneath. There is only one figure but there is no text related to these figures so it makes it hard for the reader to know what this means. There are no tables and no other illustrative diagrams. This wiki would benefit a great deal with more figures, table and perhaps a you tube video.
3. Content correctly cited.
Yes it seems the content is cited correctly. There is an extensive list of references. However there is some information that is not cited at all e.g. under Organogenesis. This needs to be cited.
4. The wiki has an element of teaching at a peer level using the student's own innovative diagrams, tables or figures and/or using interesting examples or explanations.
There are no graphs, or tables and one figure that is floating in the introduction and start of the topic. Clearly this can be improved. The wiki does use examples with Drosophilia and Mammals which is great and interesting.
5. Evidence of significant research relating to basic and applied sciences that goes beyond the formal teaching activities.
This is evident that the students have done a lot of research in this topic and are innovative with their examples using Drosophilia and Mammalia however there is still headings without content that needs to be filled.
6. Relates the topic and content of the Wiki entry to learning aims of embryology.
There is a heading on neural development but no text and some information on organogenesis which does correspond to learning aims in Embryology. However more information is clearly needed.
7. Clearly reflects on editing/feedback from group peers and articulates how the Wiki could be improved (or not) based on peer comments/feedback. Demonstrates an ability to review own work when criticised in an open edited wiki format. Reflects on what was learned from the process of editing a peer's wiki.
There seems to be editing in this Wiki however the students need to come together to talk about what is missing: i.e. introduction is missing.
8. Evaluates own performance and that of group peers to give a rounded summary of this wiki process in terms of group effort and achievement.
This is hard to tell. There seems to be an overall group effort but some sections have missing content and it either seems one student is not pulling weight or that section will be a group effort and the group has not worked on it yet.
9. The content of the wiki should demonstrate to the reader that your group has researched adequately on this topic and covered the key areas necessary to inform your peers in their learning.
Yes so far there is adequate research, a lot of references cited but some key sections are empty. It seems that the group has used the Discussion section to communicate between each other.
10. Develops and edits the wiki entries in accordance with the above guidelines.
Yes this group has edited the wiki using the guidelines.
Peer Assessment: Project 6: TGF beta Signaling Pathway
1. The key points relating to the topic are clearly described.
There are headings for key points but the information for these key points has not been added so far. There is a heading for introduction but this has not been filled.
2.The choice of content, headings and sub-headings, diagrams, tables, graphs show a good understanding of the topic area.
There are two black and white figures which are quite clear and well done. However they are not referenced.
3. Content correctly cited.
The content is not cited correctly. There is a reference section but there are no publications that have been cited listed. The figure is not referenced at all. If there is any information on the page why are there no citations at all????
4. The wiki has an element of teaching at a peer level using the student's own innovative diagrams, tables or figures and/or using interesting examples or explanations.
There are two figures. There does not seem to be any examples or explanations that show the students own innovation. A time line would help a great deal.
5. Evidence of significant research relating to basic and applied sciences that goes beyond the formal teaching activities.
This is somewhat evident but there is not enough clear information and it makes it difficult for the reader to follow the topic. There are only a few topics which have information. Clearly not enough work has been done by the students.
6. Relates the topic and content of the Wiki entry to learning aims of embryology.
Yes there is some information, which relates to the aims of embryology. However so much more is needed. The introduction has some information on how TGF beta controls certain processes in development such as proliferation, cellular differentiation, angiogenesis etc however this needs to be clearer. I am not sure where the introduction finishes and new sub headings begin.
7. Clearly reflects on editing/feedback from group peers and articulates how the Wiki could be improved (or not) based on peer comments/feedback. Demonstrates an ability to review own work when criticised in an open edited wiki format. Reflects on what was learned from the process of editing a peer's wiki.
Each section has been divided amongst the group but it seems that the members of the group have not really communicated or finished their own sections. This is not clear at all. There is no communication in the Discussion section.
8. Evaluates own performance and that of group peers to give a rounded summary of this wiki process in terms of group effort and achievement.
This is not demonstrated and it seems that the key areas have not yet been researched adequately. There is still a lot of information missing and the overall flow of this wiki is a work in process it seems. There is no information discussed between the students in the Discussion area.
9. The content of the wiki should demonstrate to the reader that your group has researched adequately on this topic and covered the key areas necessary to inform your peers in their learning.
The key areas on this wiki have been set up but there is no clear and adequate information that is correctly cited at all. It is a very poor effort thus far in terms of group research. Nothing has been cited correctly.
10. Develops and edits the wiki entries in accordance with the above guidelines.
This still has not been achieved at all. There is no editing and it seems the group has put little effort in this project.

The students put great effort in their presentation and we heard a nice variety of studies in stem cell biology and regenerative medicine today. The interaction after the presentation was great.
As general feedback I would like to advise students to:

Lab 11 Assessment
Read the following recent review article on heart repair and from the reference list identify a cited research article and write a brief summary of the paper's main findings. Then describe how the original research result was used in the review article. <pubmed>26932668</pubmed>
Cited research article from review article: <pubmed>21350179</pubmed>
Brief summary of the paper's main finding:
This paper by Porello et al. (2011)[1] appeared in Science as a report, and reports how 1 day neonatal mice can generate their heart (cardiac regeneration) after partial surgical resection, however this capacity is lost 7 days after birth. Interestingly teleost fish (e.g zebrafish) and amphibians also have the capacity for cardiac regeneration, but this occurs throughout the life of the animal. The main anatomical difference is that fish hearts are two-chambered and have a single circulation (e.g. adult zebra fish), while mammalian hearts are four-chambered and have a double circulation. Thus the only time the mammalian heart resembles a fish heart is during embryonic development, before the mammalian heart has undergone septation. The other difference is zebrafish cardiomyocytes (muscle cells that make up the cardiac muscle) are small and mono nucleated and retain their proliferative potential throughout their life, while the mammalian cardiomyocytes become bi-nucleated shortly after birth and withdraw from the cell cycle[2] . The paper's main finding is that 1 day old mice that undergo surgical resection of the ventricular apex, do stimulate a regenerative response which restores the damaged heart to its normal anatomy and function. Within the first week of postnatal life, the mouse heart loses its regenerative potential and this coincides with the developmental window that occurs after birth when cardiomyocytes become binucleate and withdraw from the cell cycle. [3]
Describe how the original research result was used in the review article
The review paper [4] mentions the study by Porello et al. (2011)[1] because they firstly describe that the primary obstacle to functional recovery of a failing or infarcted human heart is the limited proliferation capacity of cardiac muscle. Cardiac muscle unlike skeletal muscle can not regenerate. The review paper [4] mentions that the mammalian heart was believed to be a post-miotic organ (an organ that is not able to undergo mitosis) but recent studies show that adult human cardiomyocytes can be replaced but a low and detectable rate but this rate is not sufficient to compensate large scale tissue loss in the heart. So different approaches have been explored recently to try to find methods to regenerate cardiac muscle, in so cardiomyocytes have been used in regenerative medicine. Here the review article briefly describes the process of how cardiomyocytes grow during embryology. The cardiomyocytes proliferate during fatal development and also after birth in the first days of postnatal life, and this enables a huge increase in cardiac growth. Here the review articles mentioned how teleosts fish can regenerate parts of their heart after injury and it is also observed in some urodele amphibians. The article mentions the fact that neonatal mice also have some ability for cardiac regeneration and here the research article by Porello et al. (2011)[1] is cited. The review article [4] explains that since cardiac muscle regeneration is observed in neonatal mice, this capability needs to be addressed in human heart muscle in order to see if this can be used to recover human heart muscle mass and function. Interestingly the review article [4] also agrees that in order to understand human heart development and function it is necessary to investigate the regulation of cardiomyocytes in different contexts and in different species.
