stem_cell

Does treatment using embryonic stem cells (ESCs) help improve heart functionfollowing a heart attack? Each sheep in the study was randomly assigned tothe ESC or control group, and the change in their hearts' pumping capacitywas measured in the study. A positive value corresponds to increased pumpingcapacity, which generally suggests a stronger recovery.
