More stem cell wizardry – without exploiting embryos

Stem cell brain blob

Interesting news in Nature magazine yesterday re the small disorganised clump of ‘brain tissue’ generated by human stem cells; note of course that no embryos were used, but the entirely ethical iPS cells (“induced pluripotent stem cells”) derived from human skin cells. That is the true state of stem cell science: embryo exploitation and cloning remains both wrong and redundant, now we have the iPS alternative.

Note, as always, the sleight of hand by the embryo experimenters who always smuggle in the impression that embryos are still kicking goals, when they are in fact on the bench and basically irrelevant. Prof Martin Pera, an Australian spruiker for many years in favour of embryo exploitation and cloning, on this morning’s ABC AM:

Yamanaka, gentle slayer of cloning, takes the nobel prize for Medicine

Your scribe was giving a talk to a group of doctors in Sydney last night on “Ethical stem cell science & the Death of Cloning”, and on entering the warm and welcoming Irish pub I was informed of the grand news that Shinya Yamanaka had been awarded the Nobel prize for medicine.

Nice in Mice: skin cells straight to heart cells (forget embryos)

I can’t improve on my comrade David Prentice’s coverage of this latest bit of Direct Reprogramming Wizardry. I wonder if this new way of obtaining perfectly-matched stem cells (with no need for embryos or cloning, and apparently minimising the risks inherent even in iPS cells) will generate the sort of science-media interest that the futile tinkering at Geron generated…
