CD68 and hepatocellular carcinoma: In HCC peritumoral stroma, the main site of B cells (Fig. 1a), there were pronounced accumulations of S100+ DCs and CD68+ macrophages (Fig. 2a,b and Supplementary Fig. 2a), and that increased densities of these cells in the peritumoral stroma both predicted reduced survival (Fig. 2c, Supplementary Table 1; ref. 8).
