Pars distalis

Hematoxylin and eosin staining of the pars distalis reveals two general types of secretory cells, basophils and acidophils.  Basophils contain purple-staining granules; acidophils contain pink-staining, eosinophilic granules.  Cells without obvious granules are called chromophobes and may be either degranulated chromophils or reserve cells.  All cells are arranged in plates or cords with numerous intervening fenestrated capillaries.  400x
