There are other additional antigens, including CD44, CD47 (IAP), CD529 (Campath-1), CD56 (NCAM), CD90 (Thy-1), CD93, CD114 (granulocyte colony-stimulating factor (G-CSF) receptor), CD123 (IL-3RA), CD135 (FMS-like tyrosine kinase 3 (FLT3)), and CD295 (LEPR) that are also present on CML LSCs [34, 41–43]. This evidence concerns the gene CD44 and chronic myelogenous leukemia, BCR-ABL1 positive.
