New Source Of Stem Cells Found
(Undated) -- Scientists are conducting research into another potential alternative to embryonic stem cells. The "Los Angeles Times" reports researchers have converted cells from human testes into stem cells that grew into muscle, nerve cells and other tissue. The cells would not require the destruction of human embryos. Sabine Conrad of the University of Tuebingen in Germany says they're theoretically better because they can be taken directly from male patients and used to grow replacement tissue that their bodies won't reject. Cells from some of the patients were injected into mice, where they developed into tissue that included cartilage, muscles and nerve cells. The study is published in the online edition of "Nature." |
