FIGURE 1 Percentages of cells within the mammary gland epithelium labeling positively for the proliferation marker Ki67 via immunohistochemistry. Red = all labeled lobuloalveolar cells; Pink = strongly labeled lobuloaleolar cells; Dark blue = all labeled ductal epithelial cells; Light blue = strongly labeled ductal cells. Staining in lobuloalveolar cells was greater in the follicular phase (*= P<0.05), and staining in ductal cells was greater in luteal phase (**= P<0.05).

FIGURE 2 Percentages of cells within the mammary gland epithelium labeling positively for progesterone receptors via immunohistochemistry. Red = lobuloalveolar epithelial cells; Blue = ductal epithelial cells. Staining in ductal cells was lower in the luteal phase (*= P<0.05).

FIGURE 3 Percentages of cells within the mammary gland epithelium labeling positively for CPP32 by immunohistochemistry. Red = lobuloalveolar epithelial cells; Blue = ductal epithelial cells. Staining in lobuloalveolar cells was greater in the luteal phase (*= P<0.05).

FIGURE 4 Percentages of cells within the mammary lobuloalveolar and ductal cells labeling positively for estrogen receptors (ER) alpha and beta via immunohistochemistry. Red = ER-alpha in lobuloalveolar cells; Pink = ER-beta in lobuloaleolar cells; Dark blue = ER-alpha in ductal epithelial cells; Light blue = ER-beta in ductal cells. There were no differences for cycle stage, but ER-beta was always more abundant (P<.05).
