ACCESSORY MAMMALIAN REPRODUCriVE GLANDS 



407 



plasm is not as granular as in the ventral 

 prostate and appears vacuolated, particu- 

 larly in the basal region and around the 

 nuclei; the apical cytoplasm is condensed 

 and granular (Fig. 6.13, a gland from a 

 castrated male injected with testicular ex- 

 tract, illustrates essentially the characteris- 

 tics of the normal epithelium). Golgi bodies 

 ( Fig. 6.26) form large networks close to the 



luminal end of the cells (Moore, Price and 

 Gallagher, 1930). 



The striking characteristic of these cells 

 in electron microscopy (Brandes, Belt and 

 Bourne, 1959; Brandes and Groth, 1961) 

 is the great dilation of the cisternae of the 

 endoplasmic reticulum (Fig. 6.31) which 

 fill the greatest part of the cell and are par- 

 ticularly distended in the basal region. The

 dense body lies above the nucleus and below dilatated Golgi microvesicles. Arrow points to 

 collapsed ergastoplasmic sacs. (From J. C. Harkin, Endocrinology, 60, 185-199, 1957.)
