Researchers have now found a way to propagate primary human Sertoli cells in the laboratory -- the first step, say investigators, to developing an artificial human testicle for reproductive research. Derived from the testis, it has been difficult to maintain Sertoli cells, the "nurse" cells responsible for overseeing sperm production, outside of the human body. San Francisco, CA (Vocus) October 25, 2010 After more than 30 years of unsuccessful efforts by numerous investigators,...
