[Ultrastructural study of the Sertoli cell in the seminiferous tubules of a hibernating animal, Eliomys quercinus L.), living in different lighting conditions].
The ultrastructure of the Sertoli cell studied in sexually active control animals during May-June and experimental animals sexually activated by light in winter, presents the commonly described ramified aspect with an infolded nucleus, well developed Golgi complexes, rough and smooth endoplasmic reticulum, numerous microfilaments, few liposomes and lysosomal formations; In the regressed testes of hibernating animals or blinded spring animals, the Sertoli cells are more round shaped with a significant increase in number and size of liposomes, lysosomes and various necrotic bodies. These morphological changes may be in favour of the possibility of a synchronization of the function of the Sertoli cell with the spermatogenic cycle to coordinate locally the proliferation and maturation of the germ cell.
