Scientists have developed lab-grown patches composed of beating heart muscle to aid patients with advanced heart failure. Tested successfully on animals and humans, the patches, made from donor blood cells reprogrammed to mimic heart muscle cells, strengthen heart muscle and improve heart function. Fifteen patients have received the patches so far. The trial continues with promising results.
