Immunohistochemical localization of the WAP proteins, SLPI and elafin, in human endometrium. (A). SLPI immunolocalization in endometrium from the mid secretory phase. Immunoreactivity is present in the glandular epithelium and secretions. (B). Elafin immunolocalization in menstrual endometrium. Immunoreactivity is present in neutrophils infiltrating the endometrial stroma. Scale bars = 100 μm.
