The chances of restoring fertility through sperm stem cell transplant are as random as a coin toss. But a team of scientists developed a new strategy that serves as a 'weighted coin' that can ...

A research team found a novel function of FGF2 in mammalian testis. Although it has demonstrated that both GDNF and FGF2 are the self-renewal factor for spermatogonial stem cells (SSCs) in vitro, ...
