Abstract

Two separate clones of recombinant leukocyte interferon (IFLrA and IFLrD) inhibited the cloning efficiency in soft agar of the human leukemia cell lines HL-60 and KG-1. Inhibition of the growth in agar of normal human bone marrow myeloid progenitors was also observed, but this required considerably higher concentrations. IFLrA and IFLrD also inhibited the growth of HL-60 and KG-1 cells in suspension culture. This antiproliferative effect did not appear to be due to induction of maturation of these cells. Our results suggest that homogeneous preparations of interferon may be capable of exerting selective antiproliferative effects on malignant human myeloid progenitor cells in comparison to their normal counterparts.
