Immunolocalization of the enzyme cytochrome P450 aromatase in the vaginal epithelium and ovary of Spix cavy. a immunoreactivity in cells (arrow) of the connective tissue (ct); (e) epithelium in the vaginal wall at diestrus. b immunoreactivity in basal cells (b) of the epithelium in the vaginal wall (c) cornified cells of the epithelium; (ct) connective tissue in the vaginal wall at proestrus. c immunoreactivity in cells (arrow) of the connective tissue (ct); (e) epithelium in the vaginal wall at metestrus. d immunoreactivity in basal cells (b) of the epithelium; (c) cornified cells; (ct) connective tissue in the vaginal wall at estrus. e no immunoreactivity in the epithelium (e) or connective tissue (ct) in the absence of primary antiserum, negative control. f immunoreactivity in the cells of the granulosa layer (gc) of the ovary tissue; oocyte (o); positive control.
