Nature of the Spermatogenic Arrest in Dazl 2 / 2 Mice

Abstract

Dazl encodes an RNA-binding protein essential for spermatogenesis. Mice that are deficient for Dazl are infertile, lacking any formation of spermatozoa, and the only germ cells present are spermatogonia and a few spermatocytes. To gain more insight regarding the timing of the spermatogenic arrest in Dazl 2/2 mice, we studied the spermatogonial cell types… (More)
