Laminin induces the expression of cytokeratin 19 in hepatocellular carcinoma cells growing in culture

Figure 6 Blocking test of the CK19 expression in HHCC cells induced by exogenous LN. A. CK19 expression completely blocked with concentration of the polyclonal anti-LN up to 0.2 mg/L in the LN-conditioned medium (20 mg/L). B. Addition of the same amount of normal rabbit IgG having no effect on the CK19 expression. Numbers of cells expressing CK19 presented in percentages, and CK19 expression levels indicated by column colors (white, +; gray, 2+; black, 3+). ^aP < 0.05 (compared to group on the left).
