The term "stem cell" is used so freely these days in many different forums that it is difficult sometimes understand without context what scientists, politicians, ethicists and commentators are discussing. In terms of human development, the embryonic stem cell with totipotential occurs at the blastocyst stage, mainly in the first and second week of development. After this period the inner cell mass, which forms the entire embryo, will differentiate into embryonic germ layers with restricted differentiation potential.
Stem cells as well as having the capacity to differentiate into any (totipotential) or multiple (pluripotential) cell types, have the unique capacity of self-renewal.
In vitro fertilization and growth of the blastocyst, allows isolation of these cells and their subsequent use in stem cell research. It is the collection, production and possible therapeutic applications of these stem cells which has recently attracted worldwide attention.
A key step in the development of stem cell research has been the identification of cell surface markers (proteins) which identify these cells and their state of undifferentiation.
A useful guide (online PDF document) to stem cells was produced in a report by the National Institute of Health (NIH, USA, April 2009) Stem Cells: A Primer (PDF 1.89 MB) and more recently NIH has established a Stem Cell information page.

Embryonic Stem Cell
Mesenchymal Stem Cells
Recently the human GA 14 to 16 weeks fetal heart have been used as a source of mesenchymal stem cells that appear similar to human bone marrow mesenchymal stem cells (expressing CD73, CD90, CD105 and lacking expression of CD31, CD34, CD45, HLA-DR).
Human blastocyst derived stem cells
(A–D) - stepwise procedure of embryo biopsy using inverted microscope-attached micro manipulator.
(E–L) - appearance of initial outgrowth and hESC colony during the derivation procedure.
Cord Blood Stem Cell
Placental cord blood is a rich souce of haematopoietic stem cells for transplantation. Cord blood can collected at birth, with no impact on the mother or neonate, and stured in cord blood banks for later use. BBC (UK) A brief article on Cord Blood stem cells and their therapeutic potential.
Spermatogonial Stem Cell (SSC)
In the male testes are a population of spermatogonia cells that differentiate and meiotically divide to form spermatozoa cells (male germ cells).

Adult Stem Cell
[[File:Epidermis-stem cell models.jpg|thumb|Epidermis - stem cell models Adult stem cells, with pluropotentiality, are found in several body systems: intestinal epithelium, epidermis, testis and bone marrow.
- Generation of pluripotent stem cells from adult human testis "Human primordial germ cells and mouse neonatal and adult germline stem cells are pluripotent and show similar properties to embryonic stem cells. Here we report the successful establishment of human adult germline stem cells derived from spermatogonial cells of adult human testis."

Inducible Stem Cells
Inducible pluripotent stem cells (iPS) require a minimum of key defined transcription factors (Oct3/4, Sox2, Klf4, c-Myc, Nanog and Lin28) are required to be introduced into a cell to "induce" that cell to revert to a stem cell phenotype.
- Induction of pluripotent stem cells from adult human fibroblasts by defined factors.
- Generation of induced pluripotent stem cells by reprogramming mouse embryonic fibroblasts with a four transcription factor, doxycycline inducible lentiviral transduction system.

This technique involves removing the nucleus from an early stage embryo and replacing with the nucleus from another cell. If the replacement nucleus is from a somatic cell, not a gamete, the technique is also described as somatic cell nuclear transfer (SCNT). The most famous of which was the sheep "Dolly". More recently nuclei have been sourced from a number of different tissues, including those from long-term frozen animals. See also a review of this technique.
Stem Cell Regulation
Embryonic stem cell signaling regulation (mouse)
Stem Cell Markers
In order to carry out research on stem cells, it is important to be able to identify them. A number of different research groups in the late 90's generated several antibodies which specifically identified undifferentiated, differentiating or differentiated stem cells from a number of different sources and species. Note that the nomenclature in some cases is based upon the antibody used to identify the cell surface marker.
- Stage-Specific Embryonic Antigen-1 (SSEA-1) cell surface embryonic antigen which has a role in cell adhesion, migration and differentiation and is often differentially expressed during development. Can be identified by Davor Solter (monoclonal antibody MC-480) (SSEA-1).
- Stage-Specific Embryonic Antigen-4 (SSEA-4) cell surface embryonic antigen of human teratocarcinoma stem cells (EC), human embryonic germ cells (EG) and human embryonic stem cells (ES) which is down-regulated following differentiation of human EC cells. Antigen not expressed on undifferentiated murine EC, ES and EG cells but upregulated on differentiation of murine EC and ES cells. Can be identified by Davor Solter (monoclonal antibody MC-813-70) (SSEA-4)
- Tumor Rejection Antigen (TRA-1-60) Sialylated Keratan Sulfate Proteoglycan expressed on the surface of human teratocarcinoma stem cells (EC), human embryonic germ cells (EG) and human embryonic stem cells (ES).
- Tumor Rejection Antigen (TRA-1-81) antigen expressed on the surface of human teratocarcinoma stem cells (EC), human embryonic germ cells (EG) and human embryonic stem cells (ES). Both TRA antibodies identify a major polypeptide (Mr 240 kDa) and a minor polypeptide (Mr 415 kDa).
- Oct-4 (Pou5f1) gene has an essential role in control of developmental pluripotency (Oct4 knockout embryo blastocysts die at the time of implantation). Oct4 also has a role in maintaining viability of mammalian germline.
- Stem Cell Antigen 1 (Sca-1) member of the Ly-6 family of GPI-linked surface proteins (Mr 18 kDa) and a major phenotypic marker for mouse hematopoietic progenitor/stem cell subset.
- CD133, AC133, prominin 5 transmembrane glycoprotein (865 aa) expressed on stem cells with hematopoietic and nonhematopoietic differentiation potential.
- Alpha 6 integrin

Opinion on Stem Cell Use
Results from a recent Australian survey into couples' views on the use of supernumerary embryos:
- 40% (123/311) returned completed questionnaires.
- 42% most common decision was donation to research (altruistic motives and desire not to waste embryos were determinants of embryo donation).
Determinants of disposal were not wanting a full sibling to existing children and opposition of embryo research.
- 45% found deciding distressing.
- 69% approved of embryo donation to stem-cell research.
Stem Cell Fake Result
Hwang Woo-suk (Korean pioneer of stem cell research) Resigns A Seoul National University investigation of the original data in Science paper Jun (2005;308: 1777-83) "Eleven human embryonic stem cells (hESC) lines were established by nuclear transfer (SCNT; NT) of skin cells from patients with disease or injury into donated oocytes." announced 29 Dec 2005 that he had faked the results.
The journal Science retracted the original paper, the original reference with link to the erratum.
There is a hypothesis that several cancers may arise from somatic stem or progenitor cells that exist in different tissues. These cancer stem cells are called "side population" (SP) cells and have been identified in: leukemia, breast cancer and several human cancer cell lines (central nervous system, gastrointestinal tumors, retinoblastoma). There is still a "chicken and egg" problem to be resolved, in that the cancer cells may have dedifferentiated to a stem cell-like population.
A recent paper has also identified SP cells in ovarian cancer which have properties similar to stem cells.

The Australian Health Ethics Committee was approached by human research ethics committees (HRECs) seeking advice on how to review research protocols that involve stem cell research. The following guidance is interim. Formal guidelines will be developed by AHEC in the context of its review of the 1996 NHMRC Ethical guidelines on assisted reproductive technology.
