Scientists Recreate Heart in Lab

American scientists have successfully created a pumping rat heart from the collagen structure of a dead heart and heart cells from baby rats. The researchers dissolved the original heart tissue with a soap solution using a process called decellularization. When only the gelatinous-looking white collagen structure was left, the team injected it with new heart cells and were amazed to note that the muscle tissue began to contract after just four days. Doctors are hopeful that this technique will help them develop working human organs for patients that desperately need transplants to survive
