Characterization of estrous cycle in ovariectomized mice in relation to proportion of cells: (a) proestrous, showing a predominance of polynucleated and rounded cells; (b) estrous, showing decreased amount of epithelial cells and predominance of anucleated cornified cells; (c) metaestrous, containing the same proportion of leukocytes and nucleated epithelial cells, and (d) diestrous (in this case, anestrous, without permanent hormonal stimulus), containing a predominance of leukocytes in the smear. The scale bar represents 10 μm.
