When CML cells (one CP and one AP) were selected with anti-human CD45 Ab-coated magnetic beads and transplanted to NOD/SCID mouse, CML cells were engrafted equally, and Fibs were also contributed to NOD/SCID murine bone marrow, in which CD133(+)CD106(+) cells occupied 65% (CP) and 82% (AP), respectively, in the total CD34(+)D7-FIB(+) cells. This evidence concerns the gene VCAM1 and chronic myelogenous leukemia, BCR-ABL1 positive.
