Figure 5. CD133⁺CD24^lo cells phenotypically resemble 5-FU-resistant human colon carcinoma cells.

A. CD133 and CD24 expression profiles in subsets of colon cancer cells. The indicated four subsets of LS411N and SW620 cells were stained with CD133- and CD24-specific antibodies and analyzed by flow cytometry. Shown are representative images of one of two experiments. B. CD24 protein levels as shown in A were plotted as to show mean fluorescent intensity (MFI). The MFI of the four subsets of LS411N and SW620 cells were quantified and presented at the right. Column: mean; Bar:SD.
