Primitive acute myeloid leukemia cells with long-term proliferative ability in vitro and in vivo lack surface expression of c-kit (CD117).

Abstract excerpt

A hierarchy of progenitor cells is thought to exist in human acute myeloid leukemia (AML), with only the most primitive cells capable of proliferating to maintain the malignant clone. To further characterize this AML cell hierarchy, we evaluated the coexpression of CD34 and c-kit (CD117) on cells that are capable of long-term proliferation in vitro and in vivo.AML cells were sorted for coexpression of CD34 and...
