ABSTRACT:
This application concerns human pluripotent colony stimulating factor (P-CSF) also known as pluripoietin.
BACKGROUND
This work was done in part with government funding under United States Public Health Service Grants CA-32516, HL-31780, CA-20194, CA-23766 and CA-00966. Therefore, the government has certain rights in this invention.
Abbreviations
CFU-GEMM: Colony forming unit - granulocyte, erythroid, macrophage, megakaryocyte.
CFU-GM: Colony forming unit - granulocyte-macrophage
BFU-E: erythroid burst forming unit
GM-CSF: Granulocyte-macrophage colony stimulating factor
Colony-stimulating factors (CSFs) are hormone-like glycoproteins produced by a variety of tissues and tumor cell lines which regulate hematopoiesis and are required for the clonal growth and maturation of normal bone marrow cell precursors in vitro (Burgess, A. W., et al. (1980) Blood

:703-707). Pluripotent CSF is involved in the proliferation and differentiation of pluripotent progenitor cells leading to the production of all major blood cell types. This is therefore a broad spectrum CSF. It also induces differentiation of leukemic cells.
SUMMARY
This application concerns human puripotent colony stimulating factor CSF for the stimulation of proliferation and differentiation of pluripotent progenitor cells to all major blood cell types which is purified to apparent homogeneity. Its biological effects include the induction of functional markers of differentiation of normal and leukemic cells.
