USC scientist Qi-Long Ying, PhD, MSc, and a team of researchers have long been searching for biotech’s version of the fountain of youth — ways to encourage embryonic stem cells (ESCs) and epiblast stem cells (EpiSCs) to endlessly self-renew, or divide to produce more stem cells.

In a pair of studies published in Nature Communications in September and a study in The EMBO Journal in August, Ying and his team revealed some of the ways that ESCs and EpiSCs retain their pluripotency, or ability to differentiate into virtually any kind of cell. … Read More »

Can the same gene prevent and promote cancer? When it comes to liver cancer, the gene that codes for P53, a protein found in humans and many other animals, can indeed do both.

In a pair of articles published in Oncogene and the Journal of Hepatology, Qi-Long Ying, PhD, associate professor of cell and neurobiology at the Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at USC, and a team of researchers revealed that P53 can both help and harm a liver exposed to carcinogenic chemicals. … Read More »
