title: Recombinant interferon-beta 2 (interleukin-6) induces myeloid differentiation.
abstract: Human IFN-beta 2 cytokine produced in E. coli was purified to homogeneity by immunoaffinity and ion-exchange chromatography. The cytokine inhibits the growth of myeloleukemic M1 cells and induces their morphological and functional differentiation into macrophages. Differentiation was also observed in the histiocytic lymphoma U937 cells. The effect on U937 was synergized by IFN-gamma and under these conditions IFN-beta 2 produced the induction of (2'-5') oligo(A) synthetase typical to IFN action and to differentiation.
