　　U.S. company claims to make stem cells from testes

　　U.S. researchers said on Saturday they had transformed immature cells from men's testicles into powerful stem cells， which they then coaxed into becoming nerve， heart and bone cells.

　　Their work has not been assessed by standard peer-review processes， but was presented at a meeting of stem cell researchers in Valencia， Spain. If other researchers can duplicate their efforts， the study offers a possible new source of valuable stem cells.
