Mesenchymal Stem Cells Require CD73 Activity to Reduce Leukocyte Associated Inflammation Following Myocardial Ischemia-Reperfusion Injury

Nov.13, 1:30 pm, Science and Technology Hall- Basic Science Theater

Cell therapy, using the patient’s own cells to reduce damage to the heart after a heart attack, has been a hot topic. Mesenchymal stem cells are derived from the bone marrow and can’t replace heart muscle. But they do exert anti-inflammatory and anti-oxidative effects, Eric Shin, MD, Rebecca Levit, MD and colleagues show in a rat model of heart attack.

The researchers use the gel material alginate to encapsulate the cells, in a way previously described by Levit. They say this is the first study to demonstrate that mesenchymal stem cells reduce reactive oxygen species production in the heart. and that the molecule CD73, which degrades ATP/ADP into adenosine, is needed for the anti-inflammatory effect. CD73 is also a cancer immunotherapy target. Read more
