Signaling molecule crucial to stem cell reprogramming

While investigating a rare genetic disorder, researchers at the University of California, San Diego School of Medicine have discovered that a ubiquitous signaling molecule is crucial to cellular reprogramming, a finding with ...

Protein domain structures affect the quality of stem cells

The original iPS cells were reprogrammed by transducing four genes: OCT3/4, SOX2, KLF4, and c-MYC. Later experiments would show that c-MYC can be replaced with MYCL. Both are MYC proteins and thus oncogenes, but animal experiments ...

Animal-free reprogramming of adult cells improves safety

Human stem cells produced through genetic reprogramming are beset by safety concerns because current techniques alter the DNA of the stem cells and use material from animals to grow them. Now, A*STAR researchers have developed ...
