Fig. 1 — Immunohistological staining for the expressions of CD105 and CD44 in surgical specimens from PDAC and HCC patients. a The expression of CD105, a marker for neovascularization, was extremely low in the PDAC specimens compared to the HCC specimens. The quantitative data and results of the statistical analysis between the groups are shown in the lower bar graph. There was a significant difference with the vascularity between PDAC and HCC. b A higher expression of CD44, a marker for cancer stem cells was observed in the PDAC specimens compared to the HCC specimens. The quantitative data and results of the statistical analysis between the groups are shown in the lower bar graph. c There was a significant negative correlation between the expressions of CD105 and CD44 in each specimens, for both PDAC (p < 0.01, left) and HCC (p < 0.001, right)
