The fine structure of the interstitial cells in the testis germinative epithelium of Quatuoralisia malakhovi. a General view of the interstitial cells. Frames indicate the structures shown in figures b–f. b Autophagosome (aphg) and spermatozoon (sz) in the cytoplasm of interstitial cell. c Autophagosome (aphg) and flagella (flg); the frame indicates the flagellum enlarged in figure d. d Flagellum (flg) between the membranes of autophagosome. e Nucleus. f Phagosome with remnants of degenerating spermatogenic cells (arrows). g Spermatozoon (sz) captured by the interstitial cell. aphg, autophagosome; flg, flagellum; glb, globules; lum, lumen of the testis; ncl, nucleus; phg, phagosome; sc, spermatocytes; sg, spermatogonia; sz, spermatozoon; vac, vacuole
