Scientists grow heart muscle strip that beats
WASHINGTON - Scientists have grown a piece of heart muscle - and then watched it beat - by using stem cells from a mouse embryo, a big step toward one day repairing damage from heart attacks. Think of Dr. Kenneth Chien as a heart mechanic. "We're making a heart part and (eventually) we're going to put the part in," is how he describes the work by his team of Harvard and Massachusetts General Hospital researchers. Ref. Source 9
That's a big move. In half a century I'm pretty sure body spare parts will be something normal. You have a bad heart you just get a replacement, you don't have to wait for a donor anymore.
