Figure 1. Characteristics of SW620 stem cells. A, SW620 CD133+ and CD133− cells were isolated from SW620 using flow cytometry. B, Colony formation of unsorted SW620, CD133−, and CD133+ cells. C, Relative cell viability of unsorted SW620, CD133−, and CD133+ cells under oxaliplatin and 5-FU (5-fluorouracil) treatments. Data are reported as means±SD. *P<0.05 and **P<0.01 vs unsorted SW620 cells (t-test).
