Figure 10From: The spatiotemporal expression pattern of the bone morphogenetic protein family in rat ovary cell types during the estrous cycleIn situ hybridization of FS mRNA in ovaries of adult cycling rats. Brightfield (A, C, E, F, H, J, L, N) and Darkfield (B, D, G, I, K, M, O). A, B: Sections from a DI 1100 h ovary (4X) showing strongly positive GC in GF and weakly positive GC in preantral follicles (arrow heads); C, D: Positive SIC at P 2000 h (4X); E: Higher magnification of panel C showing high density of silver grains (black dots) over the SIC (40X); F to O: FS expression in CL-I during luteogenesis (4X) i.e. luteinization (E 0200 h, E 1000 h, DI 1100 h) and luteolysis (DII 1100 h, P 2000 h).Back to article page
