Localization of CaBP-28k protein in the human endometrium. Immunohistochemistry was performed to detect CaBP-28k protein in different phases in the uterine sections during the menstrual cycle (a, early-proliferative phase; b, mid-proliferative phase; c, late-proliferative phase; d, early-secretory phase; e, mid-secretory phase; f, late-secretory phase) as described in Materials and Methods. Arrowheads → endometrial epithelial cells, arrows → endometrial glandular cells. Arrows and arrowheads indicate CaBP-28k-positive regions.
