Roles of the MEK1/2 and AKT pathways in CXCL12/CXCR4 induced cholangiocarcinoma cell invasion

Figure 2 Effect of CXCL12 on the proliferation of cholangiocarcinoma cells. RMCCA1 and KKU100 were treated with CXCL12 at various concentrations (0, 50, 100 and 200 ng/mL). Cell proliferation assay was performed after 2 d by using WST-1. The absorbance at 450 nm, against a reference wavelength of 650 nm, was determined.
