Intratumoral OV6 expression is positively correlated with CD68+ TAM infiltration in HCC specimens.
(A) Representative images of H&E and IHC staining of OV6 and CD68 in HCC specimens from the training cohort are shown (n = 153; scale bars: 10, 20 and 50 μm);
(B) Results of the correlation analysis between the H-score of OV6 and cell density of CD68+ TAMs in HCC specimens are presented (n = 306; Pearson's r = 0.45; P < 0.001).
