Cytoarchitecture of the corpuscles of Stannius in hillstream teleosts, Barilius bendelisis (Ham.) and Garra gotyla (Gray)

The teleosts, Barilius bendelisis and Garra gotyla possess corpuscles of Stannius (CS) which are discrete, encapsulated bodies lying in close proximity to the mesonephros. The corpuscular cells are arranged in anastomosing cords which are separated from each other by connective tissue septa and numerous sinusoids. Light microscopically, 2 types of secretory cells comprise the CS in these species. Majority of the corpuscular cells are stainable with AF and PAS in contrast to the nonstainable cells which evince little affinity for the dyes. The fine cytoplasmic granules contained in the stainable cells are polarized on the vascular face in Barilius bendelisis.
