PROM1 and chronic myelogenous leukemia, BCR-ABL1 positive: RT-PCR analysis yielded similar results for molecular expressions between injected CML cells and the engrafted CML cells (Figure 2(a)), in which CD13 and CD33 (human myeloid markers that were also expressed in the injected CML cells) and CD34 and CD133 (human stem cell markers that were expressed in the injected CML cells) were detected in the engrafted murine bone marrow cells.
