BEDFORD STEM CELL RESEARCH FOUNDATION Massachusetts 501(c)(3) not for profit organization P: 617-281-7902 E: [email protected] W: www.bedfordresearch.org The Testis: a source of stem cells for all men? Could the newly discovered “testis stem cells” be as versatile as embryonic stem cells? Bedford is launching a major research initiative to find out. A major barrier to progress in stem cell avoid the rejection that occurs if therapies is that, similar to organ transferred cells are not a perfect tissue transplantation, the body rejects cells match to the patient’s own cells. that are not a good match for the patient. Surprisingly, stem cells from testis may Dr. Martin Dym’s research team at $280k offer a solution. In 2008, a German team Georgetown University estimates reported that they successfully derived approximately 1 in 100,000 testis stem $250K pluripotent stem cells from adult mouse cells may be pluripotent. For several $200k testis. Because of their unique ability to decades, it has been known that sperm become any type of cell in the body, are abundantly produced (billions per $150k pluripotent stem cells hold the promise of week) in the adult male testis for life, cures to many conditions, from diabetes and that the sperm arise from “sperm $136k to spinal cord diseases. Then in 2009, stem cells” termed spermatogonia. two U.S. research teams discovered However, the new reports indicate that $100k pluripotent stem cells in human testis. in addition to the spermatogonia, there $50k are pluripotent stem cells in the testis. To If pluripotent stem follow up these exciting reports, Bedford $0 cells can be derived Research scientists have launched a new from every human research initiative to answer several testis, it could launch a important questions: (1) Can stem cells Mouse Testis new era in stem cell be derived from the testis of all men?
