Abstract

Regulation of myeloid cell proliferation and differentiation in the bone marrow is mediated, in part, by the interaction of integrins on early myeloid cells with the extracellular matrix proteins secreted by stromal cells. To further define adhesive protein receptors of early myeloid cells, we examined the expression of the integrin GPIIb-IIIa (α(IIb)β3) in leukemic cell lines KG-1a, KG-1, and HL-60, that represent early stages of myeloid differentiation. All three cell lines expressed surface GPIIb-IIIa as measured by flow cytometry and by binding of 125-anti-GPIIb-IIIa monoclonal antibody. Preincubation of cells with human AB serum or platelet releasate increased GPIIb-IIIa surface expression. GPIIb transcripts were identified in all three cell lines by Northern blot analysis. Furthermore, we readily detected GPIIb transcripts in fluorescence activated cell sorted (FACS) myeloid cells from normal human bone marrow by RT-PCR. Cloning and sequencing of the PCR products established the identity of GPIIb transcripts in the leukemic cell lines and CD34+/CD33+ normal bone marrow cells. Since the normal myeloid cells also demonstrated markers corresponding to the maturational stage of KG-1a/KG-1 cells, we propose that GPIIb-IIIa may serve as a myeloid differentiation antigen and as a key integrin of myeloid precursors.
