Similarly, Figure 2 shows co-expression of TF and CSC markers (CD133 and CD44) in CD133+ H460 cells (Figure 2a and 2c) isolated from human tumor xenografts grown in mice, whereas CD133- cancer cells express only TF, but no CD44 and CD133 (Figure 2b and 2d). This evidence concerns the gene PROM1 and neoplasm.
