CD133+ gallbladder carcinoma cells exhibit self-renewal ability and tumorigenicity

Figure 4 CD133 expression in gallbladder carcinoma spheroid cells. The single cells dissociated from primary tumors or spheres were incubated with anti-CD133/1-phycoerythrin and flow cytometric analysis was performed. The percentage of CD133⁺ cells was higher in the spheroid cells. P < 0.05 vs primary gallbladder carcinoma cells.
