” I thought there was an acute shortage of those; still, this might be a breakthrough.”
I think there is indeed a shortage of donor organs — as in transplanting entire organs, but the way I read it, they can save a lot of stem cells from one organ and you need only a small amount, so you can help a lot of people with the stem cells from one donor heart.
Thanks for the clarification. I would think that would also be a safer alternative than harvesting the stem cells from the heart patient him/herself for obvious reasons.
