Fig. 2. The expression pattern and clinical significance of CD9 and CD81 in HCC.
a, b Representative images of CD9 and CD81 staining in HCC tumor tissues and adjacent normal tissues were shown. Magnification: ×100 and ×400. Scale bar = 50 μm. Column graphs indicate significantly lower expression of CD9 and CD81 in HCC tumor tissues than that in adjacent normal tissues. c qPCR analyses indicating lower KLF4, CD9 and CD81 expression in tumor tissues as compared to adjacent normal tissues were shown. d The assessment of correlation between KLF4 and CD9 or CD81 expression in HCC tissues using the method of Pearson correlation analysis (n = 34).
