Chromophobic cells and their role in extracellular transport of hormones in the bovine adenohypophysis (pars distalis).
Chromophobic cells form sheaths around secretory cells. They are in close contact with them, but occasionally leave open intercellular spaces bounded by desmosomes. It is suggested that 1. there is a reduced exposure of secretory cells to direct negative feedback exerted by hormone discharge of neighbouring cells--especially those of the same cell type, 2. chromophobic cells contribute to the formation of intralobular pathways for extracellular hormone transport.
