Protein expression of SCARB1 in the ovarian theca (A), granulosa (B), cumulus oophorus (C), and luteal cells (D) of mature mice undergoing normal estrous cycles. A–D: Confocal microscopy images of fluorescent immunohistochemistry staining of SCARB1. E–H: Confocal microscopy images of DAPI staining of nuclei. I–L: Merged image of SCARB1 and DAPI. Bars: 10 µm. Images are representative of the ovaries of three or more animals. DAPI, 4′,6-diamidino-2-phenylindole; SCARB1, scavenger receptor-BI.
