This is pretty remarkable and will hopefully lead to further exploration and research regarding using one's own stem cells to grow additional cells for cures and replacements.<p>One thing I don't fully understand is why the human body doesn't do this process on its own. If the cells can indeed be regrown or "incubated" using byproducts of the human donor her/himself and reintroduced into the body with little chance of rejection, you wonder why the infinite genius of the human body hasn't evolved to do this naturally. I suppose one might argue that the healing we ARE capable of is a form of this process and you might be right (I'm no doctor), but are their cases of something as grand a scale as restoring your own eyesight happening naturally?
