The peritumoral PI-DR positively correlates with the peritumoral expression of HPC markers. (A) Photographs of immunostaining of hepatic progenitor cell markers in peritumoral sections of tissue microarrays were taken for analyses (sacle bar = 100 μm). High and low density of EpCAM, OV6, CD133 and c-kit expression in peritumoral sections. (B) Scatterplot with fitting line shows peritumoral PI-DR positively correlates with peritumoral EpCAM, OV-6, CD133 and c-kit expression measured by IOD. Pearson correlation analysis provides correlation coefficient (r) and P-value.
