Figure 6. OSM Expression Level in CCA And the Correlations with Clinical Characteristics. (A) The protein expression of OSM in 12 paired CCA tumor (T) and adjacent non-tumor tissues (P) by western blotting. (B) Representative immunostaining images of OSM in CCA. (C) Boxplots depicted the correlation of OSM expression level and clinical characteristics; (D) Overall survival and relapse-free survival of OSMhigh and OSMlow groups evaluated by IHC;
