Some of these phenotypes do, however, appear to be specific to the type of donor cell used. For example, clones derived from cumulus cells (somatic cells that surround the egg) become obese, 19 ...

A recent study involving murine stem cells showed a recapitulation of the entire female germline life cycle, which resulted in fertilizable mouse oocytes in culture. Among approximately 200 resulta ...

Scientists Clone Mice From Adult Skin Stem Cells Date: February 12, 2007 Source: Rockefeller University Summary: Using a nuclear transfer procedure, scientists at Rockefeller University and the ...

Rare stem cell population could enable new approaches to fertility treatment. Scientists have isolated and purified rare, human germline stem cells that can be propagated over long periods of time ...

South Korean and U.S. researchers said Wednesday they had cloned a human embryo and extracted from it sought-after cells called embryonic stem cells.

In a new study published in the journal Nature, researchers in Japan report that activating just eight genes for producing gene-controlling proteins is enough to convert mouse stem cells directly ...

For females, the keratinocytes barely outperformed cumulus cells in terms of cloning efficiency: 1.6 percent of the former's blastocytes transferred to a uterus developed into a birthed pup versus ...

By activating just eight genes for transcription factors, researchers at Kyushu University have directly converted mouse stem cells into oocyte-like cells that mature and can even be fertilized ...

The promise of generating truly pluripotent stem cells from terminally differentiated adult cell types continues to captivate scientists who envision great potential for therapeutic interventions. The ...
