Regenerated kidneys filter urine!

Researchers at Massachusetts General Hospital (Boston) have successfully regenerated kidneys that were unsuitable for transplantation. They stripped the tissue of all native cells, then added donor stem cells to the scaffolding that was left behind. The re-animated kidneys successfully created urine after being transplanted into rats! The hope is to apply this technique to humans with end stage renal disease who are in need of kidney transplants and reportedly would work for the regeneration of other tissues as well.
