Odds Of Stem Cell Transplant Restoring Fertility Are as Random as A Coin Toss--Until Now
Published:10 Jun.2021    Source:Hiroshima University

The ability of stem cells to fix impaired functions of host tissues after transplantation has been a lifesaving breakthrough in treating previously incurable conditions. Much like a coin toss, however, the fate of the transplanted stem cells is unpredictable. They may choose self-renewal, grow into a different kind of tissue, or die.

 
Spermatogonial stem cells follow the same stochastic fate of unpredictability in outcomes. But a group of fertility scientists led by Hiroshima University's Yoshiaki Nakamura discovered a new method that has favorably flipped the odds and successfully reversed male infertility in mice -- showing great promise for future applications in regenerating human sperm after cancer treatment and repopulating threatened and endangered species. Results of their study are published in the journal Cell Stem Cell.
