¹⁾Abbreviations; TC: theca cells, GC: granulose cells, EC: endothelial cells, LLC: large luteal cells, SLC: small luteal cells, IHC: immunohistochemistry, RRA: radioreceptor assay. ²⁾Each stage of the estrous cycle was classified as follows; follicular (F), early-CL (I), mid-CL (II), late-CL (III), regressing CL (R), and pregnancy (P). ³⁾Each stage of the estrous cycle was classified as follows; estrus (I), metestrus (II), diestrus (III), proestrus (R), and pregnancy or pseudopregnancy (P).
