From: Ultrastructure of isolated mouse ovarian follicles cultured in vitro
FSH antral follicles: theca cells. Theca cells (TC) forming one or two layers are seen by TEM in panels a, b. Lipid droplets (L) are visible in the theca cell cytoplasm (panel c). By SEM, the cells of the theca layer (TL) are provided with a few surface expansions (panel d). Panels a-c, GC: granulosa cells; b: basement membrane. Bar is: 5 μm (panel a); 0.9 μm (panel b); 1.5 μm (panel c); 30 μm (panel d).
