Working human muscle has been grown from stem cells in the lab in a breakthrough that holds promise for sufferers of degenerative muscular diseases, scientists said on Tuesday.
The team from Duke University in North Carolina said they were the first to achieve this feat using adult skin or blood cells which were "reprogrammed" into a juvenile, versatile state.
These are called "induced pluripotent stem cells" or iPSCs. Like naturally-occurring stem cells found in embryos, they can become any other type of human cell.
