Development of neonatal mouse and fetal human testicular tissue as ectopic grafts in immunodeficient mice

Abstract

The developmental course and gene expression pattern of germ cells in allografts were similar to those in intact mice. The best time point for retrieval of mouse sperm from grafts was 5-7 weeks after grafting procedure. An accelerated development of immature human testicular cells could be achieved by ectopic xenografting of human testes.
