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).

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

In this slide show showing somatic cell nuclear transfer, as it's also known, we explain how we clone egg cells to create embryonic stem cells in our lab at Children's Hospital Boston. Unless ...

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.

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

For example, red blood cells look very different from nerve cells, but they both start out as embryonic stem cells. Adults don't have any embryonic stem cells, but they do still have stem cells ...

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 ...
