Nongranulated cells in the mouse adenohypophysis

Development and differentiation of rat pituitary follicular cells under normal and some experimental conditions with special reference to an interpretation of renewal cell system.

“…Girod, 1970;Gabe, 1972;Vila-Porcile, 1972;Dingemans and Feltkamp, 1972;Fukuda, 1973;Nickerson et al, 1974;Girod et al, 1975;Tseng and Ynthema, 1976). Dingemans and Feltkamp (1972) considered some relationship between the marginal layer cells and folliculo-stellate cells in the mouse adenohypophysis, and emphasized the striking similarity between the two cells, especially in the large region where the pars distalis was connected with the pars intermedia, i.e. at the "end" of the cleft.…”

Ultrastructural observations on folliculo-stellate cells in the pars distalis of the pituitary gland in three rodent species.

“…been reported in adults, fetuses, and also in cultures (ICHIHARA, 1967;YAMADA et al, 1967;YAMADA and YAMASHITA, 1967;YAMASHITA, 1969YAMASHITA, , 1972DINGEMANS and FELTKAMP, 1972;GOMEZ-DUMM andECHAVE-LLANOS, 1972, 1973;STOECKEL et al, 1974STOECKEL et al, , 1975KOBA-YASHI, 1975;WILSON and CHRISTENSEN, 1982). In his general review on electron microscopy of the adenohypophysis, KuROSUMi (1974) has given a description of the various granular cells of the mouse, but did not mention the folliculo-stellate cells.…”

Early Organogenesis and Cell Contacts in the Proliferating Hypophysis of the Developing Mouse

“…The Rp begins to lose its continuity with the oral cavity while precartilaginous condensation of the chondrocranium (basisphenoid and basioccipital cartilages) is evident around the Rp pharyngohypophyseal stalk. Stage IV (days [13][14][15]: the developing hypophysis is completely separated from the stomodaeum, proliferating to form a continuous complicated tree-like cavity (extensions of hypophyseal clefts) in the developing lobular PD.…”

“…Stage IV (days [13][14][15] Histology of the stage III and IV specimens sug-gested that initial endochondral ossification of the basisphenoid and basioccipital cartilages and energy-dependent programmed cell death (apoptosis) occurring in the Rp stalk were a consequence of a discontinuity of the RP with the oral mucosa (Figs. 6a-7b).…”
