Characterization of immune infiltration in sarcomatoid hepatocellular carcinoma


Figure 1. Typical pathology of sHCC and PD-L1, B7-H3 and IDO expression in the sHCC. (A) Hematoxylin and eosin staining in a sHCC sample. (B) Specimens were stained with PD-L1, B7-H3, and IDO, respectively, and the expression in sarcomatoid components, conventional HCC components, and peritumor components are shown. Graph: expression of PD-L1 and B7-H3, as well as IDO+ cell densities (cells/mm2) of each region are indicated in dot plot. *p< 0.05, **p< 0.01. NS, not significant.
