Porcine spermatogonia can develop to sperm in neonatal testicular tissue that were cryopreserved and grafted into nude mice. Live piglets were born from zygotes produced by intracytoplasmic sperm injection using these sperm (Kaneko et al. PLoS ONE, 2013). Utilization of fetal tissue will give us valuable chances for conservation of genetic resources and also for improvement of testicular xenografting. We aimed to examine whether porcine fetal testis can produ...
