There were no discernible differences in the expression of the three prominent breast cancer CSC markers, CD24 (P = 0.066; expression ratio: 0.973), CD133 (P = 0.670; expression ratio:1.02), and CD49f (P = 0.431; expression ratio: 0.907) between the ROR1-high and -low groups (Fig. S6A). This evidence concerns the gene CD24 and breast carcinoma.
