Well, its just another example why the eSC = human argumentation is BS. A human is a fully developed nervous system, not some cells. Given some vectors, we could create iPS from pretty much any body cell and then probably a human from that (if we had a sufficient bioreactor). You can also let them divide, seperate them and now you have 2 - (some big number) humans. Cells or organs are no humans. People that think that cells are the same as a grown human may have a ethical problem here, but honestly, thats their problem.
