New heart built with stem cells
An entire functional heart was created using a heart ‘shell’ and stem cells. This has been done in the rat & pig, with hopes of using a pig’s heart ‘shell’ for people. Livers, kidneys, and pancreas (muchharder) are in the works.
They “injected the empty sac with heart cells from newborn rats. Within days, the cells had multiplied to flesh out the heart, which began beating on its own.
