Production of several proteins by rat Sertoli cells is dependent on the stage of the cycle of the seminiferous epithelium. The authors have determined steady state levels and follicle-stimulating hormone responsiveness of three Sertoli cell products in culture media of rat seminiferous tubule segments at different stages of the epithelial cycle: SGP-2 (sulfated glycoprotein-2), alpha 2-macroglobulin, and testibumin. Basal SGP-2 levels were twofold higher in stages VII through VIII compared with stages XIII to I to VI (P less than 0.05). Highest basal alpha 2-macroglobulin levels were found in stages II through VIII; this was about 35% greater than in stages XIII through I of the cycle (P less than 0.05). Basal testibumin levels were twofold higher in stages II through VI compared with stages IX through XII of the cycle. Follicle-stimulating hormone had no effect on SGP-2, but by contrast it (50 mg/L) increased the level of alpha 2-macroglobulin significantly (P less than 0.05) in stages XIII through I. Follicle-stimulating hormone treatment (10 mg/L) elevated testibumin levels at each stage-pool by about 40% (P less than 0.05). The current results using staged tubular segments in vitro demonstrate cyclic basal steady-state levels of the three proteins along the seminiferous tubules and follicle-stimulating hormone regulation of alpha 2-macroglobulin and testibumin.
