This is incredible stuff! The following video embedded here is a CBS News segment discussing advances in cell regeneration and the future of growing limbs, organs, etc, from the body's own cells.
In the future, this could be the cure for heart disease, kidney disfunction, hepatic livers and so on!
Watch as they create a mouse heart using an ink-jet printer! No joke! The printer is used to spray heart cells in the correct pattern using 3D models of the functional heart.
Thanks to Roman for this video!
