| Type | MGI:General | Description | at P21, mutants show Sertoli cells with slightly vacuolated cytoplasm at P56, defects in seminiferous tubule epithelium are often associated with shrinkage of the apical processes of Sertoli cells, their disconnection from the surface of germ cells and paucity of mature spermatids at P56, degenerating Sertoli cells of mutants are electron-dense, conspicuously shrunken, and have a foamy cytoplasmic appearance; many are round with small nuclei that have deeply folded surface configurations |
