CHAF1A and immune cell infiltration. A: Typically microscopic image of multiple immunofluorescence staining for surface biomarkers of immune cells. 1: CD8; 2: CD56; 3: CD68 (green) and HLA-DR (red); 4: the reconstructed image for all biomarkers. B and C: Correlations between CHAF1A IHC score and the densities of immune cells in the tumor parenchyma (B) and stroma (C), respectively. IHC: immunohistochemistry
