Stem Cells http://kunc.org en Scientists Grow A Simple, Human Liver In A Petri Dish http://kunc.org/post/scientists-grow-simple-human-liver-petri-dish Japanese scientists have cracked open a freaky new chapter in the sci-fi-meets-stem-cells era. A group in Yokohama <a href="http://dx.doi.org/10.1038/nature12271">reported</a> it has grown a primitive liver in a petri dish using a person's skin cells.<p>The organ isn't complete. It's missing a few parts. And it will be years --maybe decades — before the technique reaches clinics.<p>Still, this rudimentary liver is the first complex, functioning organ to be grown in the lab from human, skin-derived stem cells.

The fingerprint will be gone, and the tip may look a bit strange. But the flesh, bone and nail could return.<p>Now biologists at New York University have figured out just how this lizard-like regeneration happens in mice.

But the work also raises a host of ethical concerns.<p>"This is a huge scientific advance," said <a href="http://www.childrenshospital.org/cfapps/research/data_admin/Site92/mainpageS92P0.html">Dr. George Daley</a>, a Harvard stem cell scientist who wasn't involved in the work.
