Abstract Junctional devices in Sertoli cells conform the blood-testis barrier and play a key role in
maturation and differentiation of germ cells. The spacial distribution of ectoplasmic specializations of Sertoli
cells was studied by β-actin immunolabelling, using laser confocal and transmission electron microscopy. For
confocal microscopy, β-actin immunolabelling of ectoplasmic specializations was studied over the background of either prosaposin or glutaredoxin immunolabelling of the Sertoli cytoplasm. Labelling was found
near the basal lamina, surrounding early spermatocytes (presumably in leptotene-zygotene) or at one of two
levels in the seminiferous epithelium: (1) around deep infoldings of the Sertoli cell cytoplasm, in tubular
stages… More >
