Researchers Create Beating Heart In Lab 258
Sunday Scientist writes "Minnesota researchers have created a beating heart in the laboratory. In a process called whole organ decellularization, they grew functioning heart tissue by using dead rat and pig hearts as a sort of flesh matrix, and reseeding them with a mixture of live cells. The goal is to grow replacement parts, using their own stem cells, for people born with defective tickers or experiencing heart failure."

Which is possibly even cooler, and I'm sure you can find 50k hearts a year in the US that wouldn't normally be donatable because of time constraints. (A heart is (normally!) only good for 4 hours after death or removal iirc). And even beyond saved lives, we can hopefully get a better quality of life too, since there should be less time waiting for a transplant with a half dead body.
Hmm, do modern artificial hearts last 8 days reliably? And would a diseased heart be practical?
What about organ rejection issues, will those be causes by the dead heart, the stem cells, both?

A friend of mine was working in a hospital when some old and ill VIP had a heart failure and he not only got a replacement right away (while others died waiting for a replacement for months), no, he also got a second heart when the first one was rejected by his immune system within a day. Well, he died anyway from unrelated causes soon after, but I can't get over the vision of two otherwise perfectly healthy normal guys dying just because two hearts were *wasted* this way. I want to vomit each time I have to think of that event.

Unfortunately, they also consider that, if they ever spent any money on the construction or operation of the facility, they've "paid for it" sufficiently that no stem cell research can be done there. That eliminates virtually all medical research facilities - certainly all of 'em that are attached to universites and medical schools.
(Now if it were up to me the enforcement of that would consist of charging a higher overhead rate - calculated to replace the federal contribution to facility construction and operation under normal accounting principles - to any project that came under the federal ban. But it's not up to me. And the obvious intent of congress was to do their best to ban the research, rather than just pull federal funds.)
