Oct4 Gene Expression in Primary Colorectal Cancer Promotes Liver Metastasis

Figure 4

Oct4 protein and mRNA expression of cell lines and iCCs. (a) Representative staining of Oct4 in xenograft models: subcutaneous tumor and liver metastasis. Oct4 protein expression of subcutaneous tumor was high in HCT116 and 0821siCC, which had high liver metastasis-forming ability, compared with DLD1 and 603siCC. Oct4 protein expressions of liver metastasis formed by HCT116 and 821siCC were also high. DLD1 and 603siCC did not form liver metastasis. (b) Oct4 mRNA expression was high in HCT116 and 821siCC compared with that in other cells (, ). Scale bar, 100 μm.
