The expression of Lewis y, CD44, CD147, Human epididymis protein 4 (HE4), integrin α5, β1, αv and β3 in chemotherapy resistant group and chemotherapy sensitive group of EOC samples. Representative immunostaining for (A, E) Lewis y, (B, F) CD44, (C, G) CD147, (D, H) HE4, (I, M) integrin α5, (J, N) integrin β1, (K, O) integrin αv and (L, P) integrin β3 in (A-D, I-L) chemotherapy resistant ovarian cancer group and (E-H, M-P) chemotherapy sensitive EOC tissues. All of these immune markers are predominantly found on the membrane of tumor cells. Scale bar: 50 μm.
