Resumo
We studied proliferative activity of colorectal cancer cells with different expression level of CD133 molecule associated with cancer stem cells phenotype. Analysis of BrdU incorporation into Caco-2 and HT-29 cell lines showed that the percentage of cells in the DNA synthesis phase in the CD133+/high population is higher than in CD133—/low population. The expression of proliferation marker Ki-67 and the percentage of Ki-67+ cells were also higher in the CD133+/high population. Colorimetric analysis with crystal violet dye showed that the number of cells after 10-days culturing was higher in the CD133+/high population in both cell lines. These findings suggest that cells with high level of CD133 expression are characterized by higher proliferative activity, which can contribute to the tumor progression.
