Cytodifferentiation of ACTH cells in pars distalis adenohypophysis cerebri of buffalo foetii: An immunohistochemical study
2006
Sethi, R.S. | Saighal, R.P.
The hypophysis of 19 buffalo (Babalus bubalis)foetii ranging from 30 mm to 630mm in crown-rump length (CRL)were used for the study.The serial sections of 5um thickness were treated with labeled Avidin Biotin method. Adrenocorticotrophic harmone producing (ACTH) cells were observed at 60mm and onward stages. The cells, in a follicular arrngement were placed peripherally and close to the relatively larger sinusoid at 75 mm stages. At 85 mm stage the cells were observed in groups and cords in the lateral region of the gland. The cells were distributed throughout the glands at 240 mm stage. At 320 mm stage the cells occurred singly or in a larger groups and a few cells were observed in zona tuberalis, however, no cell was evidenced in pars tuberalis. The cells were observed in groups and cords mainly in the lateral zone at 482 mm stage and were distributed throughout the gland singly or in small and large groups at 630 mm stage.
