Mice That Express Enzymatically Inactive Cathepsin L Exhibit Abnormal Spermatogenesis1

Abstract excerpt

The finding of large, stage-specific changes in secretion of procathepsin L by rat Sertoli cells has led to the hypothesis that this proenzyme promotes the survival, replication, or differentiation of spermatogenic cells. Experiments described herein used a mouse model to test this hypothesis. To prove that mice are appropriate for this purpose, we first demonstrate that mature mouse Sertoli cells express...
