title: Chromophobic cells and their role in extracellular transport of hormones in the bovine adenohypophysis (pars distalis).
abstract: 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.
