How Stem Cell Therapy Is Being Studied for Heart Repair
Heart muscle has a stubborn limitation. Once a portion of it dies after a heart attack, the body does not rebuild that lost tissue in the way it heals skin or liver. The damaged area is replaced largely by scar, and scar does not contract. That simple fact has driven two decades of intense interest in Stem Cell Therapy for heart repair. The hope has been compelling from the start: if clinicians could place the right cells into an injured heart, perhaps they could
