Origin and Development of the Germinative Epithelium and Sertoli Cells in the Human Testis: Cytological, Cytochemical, and Quantitative Study

A revised model for spermatogonial expansion in man: lessons from non-human primates

“…Several studies have proposed alternate types of A-spermatogonia in the human testis and electron microscopic studies were unable to confirm the hematoxylin-based distinction of only two types of A-spermatogonia in the human testis (Roosen-Runge & Barlow 1953, Mancini et al 1960, Schulze 1978. We have revisited the proposed model and started an attempt to transfer our recent findings from the rhesus monkey into the human situation.…”

Glycogen, Phosphorylase and Glycogen Synthetase in Hamster Testis During Postnatal Development

“…In spite of a relatively abundant literature on testicular glycogen, no quantitative data are available on this subject. Only Mancini, Narbaitz & Lavieri (1960) have studied the localization of glycogen in human testis during the postnatal development. Alfano & Swartz (1955) studied total glycogen in hamster testis during postnatal development, though no data on the quantity or localization were given.…”

Age and Seasonal Changes in the Testis of the Ferret

“…The present observations suggest that the same pattern of Sertoli cell distribution holds good for the ferret also. Hamster (FEAGANS, CAVAZOS and EWALD 1961) and human Sertoli cells bave been reported to contain a moderate amount of glycogen (ARZAC 1950, ELFTMAN 1952, LONG and ENGLE 1952, MANCINI, NOLAZOCO and BALZE 1952, MONTAGNA 1952a, b, MONTAGNA and HAMILTON 1952, FAWCETT and BURGOS 1956, MANCINI, NARBAITZ and LAVIERI 1960 which in man apparently appears after pubertry (MANCINI et al 1960). The cytoplasm of bull, ram and boar Sertoli cells, on the other hand, contain only a few PAS-positive granules which were not digested by saliva (CAVAZOS and MELAMPY 1954).…”
