the other source of stem cells is from human testicle..
Weill Cornell Medical College researchers used spermatogonial progenitor stem cells, or SPCs, obtained from mice testes to form so-called multi-potent adult spermatogonial-derived stem cells. Those cells developed into endothelial cells and tissue, as well as cardiac cells, brain cells and a variety of other cell types.
Prior research used genetic manipulation to reprogram adult cells derived from connective tissue to acquire stem-cell potential, differentiating into various organ-specific tissues, the scientists said. However, that reprogramming method -- called "induced pluripotency" -- carried an increased risk of transforming into malignant cells.
