Stem Cells From Testicles

Testicles: A New Source of Stem Cells?
Men's testicles contain certain cells that seem to be as versatile as embryonic stem cells, the Associated Press reports. A study, published in Nature, suggests that the cells could possibly be used to help grow replacement tissues for other parts of the body. Using these cells would be far less controversial than using embryonic stem cells, which are harvested in a process that destroys embryos. The German researchers who conducted the study were able to change the testicular cells into heart, bone, pancreatic, and nerve cells. The catch: The benefits of testicle-derived stem cells would probably apply only to men.
