Follicular analysis of cycle matched ovaries. Morphological quantification of wild type and itchy ovaries during diestrus. Significant differences denoted by asterisks. Images are representative photomicrographs of an ovary stained with H&E from a wild type female in diestrus (top) and itchy female in diestrus (bottom). Each type of follicle is indicated as such: primary (1), secondary (2), antral (An), atretic (At), and corpus luteum (CL). Images illustrate the similarity between the number of follicles from the mice of the two genotypes, and the greater number of CL in the wild type ovary. Scale bar is 500 µm.
