Protein is key to embryonic stem cell differentiation
Date:3/18/2009

tion. Feng and colleagues screened chemical libraries and identified a small-molecule inhibitor of Shp2 that, in small doses, partially inhibits differentiation in both mESCs and hESCs. Taken together, these results suggest a conserved role for Shp2 in ESC differentiation and self-renewal in both mice and humans.

"This opens the door for new experimental reagents that will amplify the self-renewal process to create more stem cells for research and potential clinical use in the future," Dr. Feng added. "This research also suggests that comparative analysis of mouse and human embryonic stem cells will provide fundamental insight into the cellular processes that determine 'stemness,' a critical question that remains to be answered in the stem cell biology field."
