Photomicrographs illustrate the characteristic cytology of vaginal smears obtained from control rats. In rats, the cycle stages were classified as proestrus (PRO), characterized by a predominant population of nucleated epithelial cells (green arrow); estrus (EST), distinguished by cornified cells (white arrow); metestrus (MET), identified by the presence of both cornified epithelial cells (white arrow), nucleated epithelial cells (green arrow) and leukocytes (black arrow); and the diestrus stage (DIST), where leukocytes predominate alongside nucleated epithelial cells (green arrow).” 400 × magnification; bars = 50 μm
