Somatic stem cells are present in many fetal and post-natal tissues. Somatic stem cells are also capable of self-renewal and, with appropriate signals, differentiate into various cell types from ...

Embryonic stem cells are derived from the inner cell mass of the blastocyst, an early-stage embryo that is approximately four to five days old in humans and consists of 50 to 100 cells.

Adult stem cells are undifferentiated cells found throughout the body that divide to replenish dying cells and regenerate damaged tissues. Also known as somatic stem cells, they can be found in ...

The research breakthrough, led by Shoukhrat Mitalipov, Ph.D., a senior scientist at ONPRC, follows previous success in transforming monkey skin cells into embryonic stem cells in 2007.

Embryonic stem cells. ... Recently, a new category of stem cells has emerged that originate from somatic cells and can be reprogrammed by scientists back to their pluripotent stage.

In the in vitro differentiation of ovarian somatic cells and PGCs from embryonic stem cells (Panel B), the aggregation of embryonic stem-cell–derived fetal ovarian somatic–like cells with PGC ...

So important, in fact, that over the past couple of decades, scientists have devised ways to reprogram non-reproductive cells, also known as somatic cells, into embryonic stem (ES) cells known as ...

Embryonic stem cells are “pluripotent” — that is, they are believed to have the potential to develop into any tissue in the human body, ... somatic cell nuclear transfer.

The first embryonic stem cells were isolated in mice in 1981. ... The news reopens the contentious debate over somatic-cell nuclear transfer, which is sometimes referred to as therapeutic cloning.

Stem cells are basic cells that can become almost any type of cell in the body. Human stem cells can come from an embryo or an adult human. They have many possible uses in science and medicine ...

Now, in a giant leap forward for stem cell research, a team of scientists has managed to produce embryonic stem cells in a manner that does not involve an embryo at all.

Embryonic stem cells are derived from the inner cell mass of the blastocyst. Embryonic stem cells in culture are capable of self-renewal without differentiation and are able to differentiate into ...
