title: Renewal of Leydig cells in the neonatal and adult monkey: a radioautographic study.
abstract: The populations of interstitial cells in the testis of three 2-3 month old monkeys and of three 5-6 years old adults (Macaca fascicularis) were analyzed: percentage, mitotic index and labeling index after 3H-thymidine injection. In the young monkey and the adult well differentiated Leydig cells incorporate the precursor as fibroblast-like cells. This demonstrates their ability of renewal.
