Fig. 5From: Good things come to those who mate: analysis of the mating behaviour in the menstruating rodent, Acomys cahirinusComparative vaginal cytology from the early (A) and late (B) luteal phase. The early luteal phase cytology contained a mixture of cornified epithelial cells (CECs; arrow), leukocytes (circle) and nucleated epithelial cells (NECs; square). Late luteal phase cytology was dominated by leukocytes with a comparatively smaller number of CECs and no NECs. Scale bars = 100umBack to article page
