Strong expression of CD133 is associated with increased cholangiocarcinoma progression

Figure 5 Invasion assays of CD133⁺ and CD133^- RMCCA1 cells. A: Invasion assays of CD133⁺ and CD133^- RMCCA1 cells were performed using the Biocoat Matrigel invasion chamber. Results are reported as the percentage of cell invasion, where the number of cell invasion from CD133⁺ RMCCA1 cells is set as 100% cell invasion. Data is represented as the mean ± SD of three independent experiments (^bP < 0.001); B: The morphology of CD133⁺ and CD133^- RMCCA1 cell invasion is demonstrated under a phase contrast microscope at 200 × magnification.
