Medical breakthrough: Bioengineered heart tissue
from By Karen SC Ashley
For patients with heart damage, the best treatment option right now is an organ transplant. But even then, the patient waiting list for an organ donor is seemingly endless. To confound matters, patients can encounter complications after heart transplantation. With new research, the ideal solution — repairing the heart — may soon be possible. To mimic the heart's powerful mechanical action, scientists needed to engineer an artificial cardiac tissue similar in elasticity and biological properties to the native heart. And the breakthrough scientists have long been waiting for has arrived — 3-D-engineered heart tissue that beats.
