Many thanks to Patrick for this:
They've just approved research in Bristol into using adult stem cells to treat heart attack patients (see today's Guardian)-amazing stuff really. No human embryos, or pig eggs with human nuclei involved. And this is happening now! How long before we can inject embryonic stem cells into people's hearts? Why would we want to?
If anyone can find the link, then I'd be enormously grateful.
UPDATE: Many thanks to Patrick again. Here is the link.
