After exposure of untreated cells to paclitaxel-derived supernatants for 4 days, both CD44high/CD24-/low and ALDH-positive subpopulations in SUM149 and MDA-MB-231 cells (triple negative breast cancer – TNBC), and SUM190 (inflammatory breast cancer) cells increased significantly by 2-3 fold (Figure 1b; Supplementary Figure 1, flow cytometry). The gene discussed is CD24; the disease is triple-negative breast carcinoma.
