American Society for Cell Biology (ASCB) at 48th Annual Meeting, Dec. 13-17, 2008, demonstrate that a single adult stem cell can self-renew and repair tissue damage in mammal.

This adult stem cell successfully restored function to mice damage muscle tissue in hind limb.

The adult stem cells were isolated from a mixed cells in skeletal muscle of mice(MusSC). These stem cells live just under the membrane that surrounds muscle fibers.

According to scientist Helen Blau, detection of the cells by bioluminescence is a breakthrough, they will able to learn lots more. They could see the responses and could monitor the dynamics of the cells.

Scientists could even able to duplicated or cloned the cells in lab. Like the original MuSC, the cloned copies were intact and also capable of self-renewal.

Scientists hope that this findings could have a wide impact in treating not only a variety of muscle wasting diseases such as muscular dystrophy but also severe muscle injuries or loss of function from aging and disuse.
