Researchers Identify Gene Linked To Sperm-producing Stem Cells In Mammals

Researchers have identified the first gene linked to the productivity of the stem cells that produce sperm in mammals. The discovery was made by applying the latest laboratory methods to a strain of mice restored from embryos frozen since the early 70s. The findings, which could someday have implications for infertility, contraception, and stem cell transplantation therapy, will be published in the June issue of Nature Genetics.
