Nobel prize

Dr Robert G. Edwards was awarded the Nobel Prize in Medicine or Physiology in 2010 in the development for the in vitro fertilization.

The studies show that using the natural conception is way better than using the assisted reproductive techniques (ART). Methods of ART include IVF (in vitro fertilization) or intracytoplasmic sperm injection (ICSI) where the sperm does not pass its natural way. With changes to the hormones in the body allowing myosis and mitosis to occur can change or have improper copying of the chromosomes. This measures the congenital abnormalities and comparing it to natural conception. It was found that there was a common trait of each method of ART; such as IVF had higher number of heart disease and DDH with renal reflux. However there was no evidence or substantial proof that the ART and were able to be compared to natural conception. http://www.ams.ac.ir/AIM/NEWPUB/12/15/4/0011.pdf

The difference between gestational age and the post-fertilization age is that gestational stage is the time between the last menstrual cycle to the conception. The post fertilization age is the time since the fertilization to the current time. the gestational age is about 2 weeks greater than the post-fertilization age.

Gestational age is used because of the developmental age and the calender age my be different. Also the date of the last menstrual cycle can easily be determined easily and clearly, where as post-fertilization age it has to be inferred.

The somite differentiation

Somites can differentiate into dermomyotome and sclerotome. Sclerotomes will develop into the vertebrae. This is from the sclerotome wrapping around the notocord, and around the neural tube. Dermomyotome, this will then divide into two subgroups; the dermatome and the myotome. The dermatome will develop into the dermis of the skin, whereas the myotome will from the muscles of the limb buds, then start to form limb muscles

Two types of invasive prenatal diagnostic techniques related to the placenta is that of Chroionic Villus Sampling (CVS)and amniocentesis.

  • Chroionic Villus Sampling allows the exclusion of Down Syndrome and cystic fibrosis

  • Amniocentesis also allows the exclusion of Down Syndrome and spina bifida.

Cord stem cells

Lately there has been a great debate on where a good source to get stem cells from. The idea of using the umbilical cord blood stem cell is that it was believed that the cell is most naive, as it lacks a check point. With using umbilical cord stem cells they have found that the most effective, as embryonic stem cells came from the inner cell mass of the blastocyst. This had meant that in order to retrieve the cells, you had to destroy the embryo. This had a whole new problems in ethics, religion and political. With this way, the mother nor the child is harmed. These cells are in the stage between becoming a adult stem cell and the embryonic cell.

Using stem cells in repairing a wide range of pathological disorders. They have found that using the cord stem cells was seen to have some regenerative capabilities as it had been seen in a patient to have improved sensory perception. With this in its early stages in neurological pathways, other forms have been shown to have some success such as using it for rheumatoid arthritis. http://www.ane.pl/pdf/7037.pdf http://arthritis-research.com/content/pdf/ar3187.pdf
