Fig. 7From: Fusion with stem cell makes the hepatocellular carcinoma cells similar to liver tumor-initiating cellsTumorigenicity-related gene expression analysis. The tumorigenicity-related gene expressions were detected by qPCR. a CD44 is a cell surface molecule that affects tumorigenesis. EpCAM is the activator of WNT pathway, which is important in cancer cells. b PCNA and Ki67 are tumor proliferation cell nuclear antigens. All of these genes are highly expressed in the fused cells (p < 0.05)Back to article page
