Stem cell-secreted protein can be given to improve heart function after experimental heart attack

Heart tissue and stem cells spring into action to begin repairing muscle damaged in a heart attack, and researchers found that a protein naturally produced in the body may potentially play a role in accelerating heart muscle repair. Giving the right dose of this protein named secreted frizzled related protein 2 (sfrp2) in studies of rats helped to prevent heart failure and reduce collagen layering that can form thick scar tissue.
