Lab-grown heart muscles transplanted into a human for the first time
Researchers in Japan have successfully carried out the world's first transplant of lab-grown heart muscle cells, in a move which could significantly reduce the need for heart transplants. To grow the heart muscle cells, the scientists from Osaka University first took adult stem cells and reprogrammed back into their embryonic-like state. From this point, the researchers were able to coax the cells into becoming whatever form they wanted -- in this case, heart muscle cells.
