Figure 1From: NF kappaB expression increases and CFTR and MUC1 expression decreases in the endometrium of infertile patients with hydrosalpinx: a comparative studyCFTR, NF KappaB and MUC1 immunohistochemical staining in the endometrium. Representative images of positive control CFTR, NF KappaB and MUC1 immunostaining (A-C) and negative control CFTR, NF KappaB and MUC1 immunostaining (D-F), respectively. CFTR, NF KappaB and MUC1 immunostaining in the endometrium of control infertile patients without a hydrosalpinx (G–L) and infertile patients with a hydrosalpinx (M–R). Endometrial tissues in the proliferative (D–I, M–O) and secretory (J–L, P–R) phases are shown for both groups; ×400 magnification.Back to article page
