From: Ultrastructure of isolated mouse ovarian follicles cultured in vitro
FCS follicles: theca cells. A thin theca cell layer (TL) is observable by SEM around the granulosa layer (GL) in panel a. Theca cells (TC) forming one or two-three layers are seen by TEM in panels b, c. Panels b, c, GC: granulosa cells; b: basement membrane. Panel c, M: theca cell mitochondria; L: theca cell lipid droplets. Bar is: 30 μm (panel a); 1 μm (panel b); 0.5 μm (panel c).
