STICKY GEL HELPS STEM CELLS HEAL RAT HEARTS

Meta Zarnik

 

The findings, described in the December 2015 issue of Biomaterials, offer a potential first step to a new way to heal human hearts after heart attacks as well. Researchers have tried to improve stem cell retention in the heart by injecting millions, only to have a mere 10-to-20 percent stick around an hour after injection. A sticky, protein-rich gel created by Johns Hopkins researchers appears to help stem cells stay on or in rat hearts and restore their metabolism after transplantation, improving cardiac function after simulated heart attacks, according to results of a new study.
