In this model, the expression of CCL3 but not those of other chemokines were increased [89], in contrast to the previous report that in addition to CCL3, CCL4, and CXCL12 expression was enhanced in bone marrow of inducible BCR-ABL transgenic mice, which developed CML [68]. This evidence concerns the gene CXCL12 and chronic myelogenous leukemia, BCR-ABL1 positive.
