Study sheds light on genetic 'clock' in embryonic cells

As they develop, vertebrate embryos form vertebrae in a sequential, time-controlled way. Scientists have determined previously that this process of body segmentation is controlled by a kind of "clock," regulated by the oscillating ...

Researchers discover how tiny sugars regulate stem cells

(Phys.org)—Embryonic stem cells hold great promise as a potential cell-based therapy for a myriad of serious diseases, but there is still much to learn before they become a regular part of the doctor's toolkit. Scientists ...

Amniotic fluid yields alternatives to embryonic stem cells

Stem cells found in amniotic fluid can be transformed into a more versatile state similar to embryonic stem cells, according to a study published today in the journal Molecular Therapy. Scientists from Imperial College London ...

Stem cells poised to self-destruct for the good of the embryo

Embryonic stem cells — those revered cells that give rise to every cell type in the body — just got another badge of honor. If they suffer damage that makes them a threat to the developing embryo, they swiftly fall ...

World's first chimeric monkeys are born

Researchers have produced the world's first chimeric monkeys. The bodies of these monkeys, which are normal and healthy, are composed of a mixture of cells representing as many as six distinct genomes. The advance holds great ...
