title: Cytochemical localization of phosphatases in the germ- and Sertoli cells of Odontophrynus cultripes (Amphibia, Anura, Leptodactylidae).
abstract: Ultrastructural cytochemical techniques were used for the localization of phosphatases in spermatid and spermatozoon, as well as in Sertoli cells of Odontophrynus cultripes (Amphibia, Anura, Leptodactylidae). Acid phosphatase was found in the acrosome. Thiamine pyrophosphatase was observed in the Golgi cisternae and in the tail spermatozoon surface. Glucose-6-phosphatase was located in the membrane complex of the acrosomal region. Already, in the Sertoli cells acid phosphatase was located in the lysosomes and glucose-6-phosphatase was observed in association with the endoplasmic reticulum and Golgi complex. These observations support the idea that various phosphatases may play some role in spermatid differentiation and in the interactions germ cells--Sertoli cells during spermiogenesis process.
