Stem Cell TANSTAAFL

Big surprise the MSM forgot to mention the recent stem cell breakthrough was not without its problems:

Now the Kyoto team, led by biologist Shinya Yamanaka, reports that it can reprogram adult skin cells in both mice and humans into induced pluripotent stem (iPS) cells without c-Myc. Further, in a mouse model, when the cells are incorporated into an embryo, the adult animal faces a dramatically lower risk of developing cancer. But there's a catch: "We found that the omission of [c-Myc] resulted in fewer numbers of iPS cell colonies," Yamanaka told ScientificAmerican.com via e-mail. "The process also takes longer. However, most of resulting iPS cells are very good."

And, as they say, "that's not all, folks!" Still, it would seem progress of a sort, although it definitely looks like we're quite a long way from being able to grow organs in a jar.
