In utero, the blastocyst implants and all three embryonic germ layers are formed during gastrulation. Somatic stem cells are present in many fetal and post-natal tissues. Somatic stem cells are ...

Neuronal stem cells produce a variety of nervous system tissue, mostly during early embryonic development ... from the cell of an adult animal.) A somatic cell could be taken from the recipient ...

What Somatic Cell Types Can Be Reprogrammed ... Induction of pluripotent stem cells from mouse embryonic and adult fibroblast cultures by defined factors. Cell 126, 663–676 (2006).

the ISS team looked at how adult stem cells — another name for somatic stem cells — behave. Compared to embryonic stem cells (and the advantages associated with their research), they're more ...

Scientists have identified a previously unknown type of neural stem cell (pNSC) that exists outside the brain and spinal cord ...

Advocates counter that adult stem cells, useful as they may be for some diseases, have thus far proved incapable of producing the full range of cell types that embryonic stem cells can.

"While many regulators of embryonic stem cells have been identified, the same cannot be said for adult somatic stem cells, where our understanding of their maintenance and regulation are not as well ...

For decades, scientists assumed that neural stem cells (NSCs) only occur in the brain and spinal cord. A new international ...

Most of the human induced pluripotent stem cells stored at major ... Researchers make hiPSCs by harvesting somatic cells—often from skin—from a person and then reprogramming them to enter an embryonic ...

In 2005, the National Academies released the book, Guidelines for Human Embryonic Stem Cell Research, which offered a common set of ethical standards for a field that, due to the absence of ...

These are adult somatic (non-reproductive ... factors trigger changes that effectively turn each cell into an embryonic stem cell, which can then be coaxed into any desired cell type found ...
