Immunolocalization of carbohydrate epitopes MECA-79 on the apical surface of the luminal epithelial cells. a - thin and b - normal endometrium; (1) - luminal cells and (2) - glandular cells. Negative controls were performed without primary antibodies (c) and with isotypic rat IgM (d). Positive control - lymph nodes in breast cancer (e). Magnification: × 400. Histograms demonstrate relative expression of carbohydrate epitopes MECA-79 in thin (n = 14) and normal (n = 18) endometrium. The bar represents optical density as a mean value ± standard deviation. *p < 0.05 compared to normal endometrium (f)
