Human interleukin-3 is an E. coli-derived recombinant protein corresponding to full-length mature human interleukin-3. Interleukin-3 supports the formation of multilineage colonies in the early development of multipotent haematopoietic progenitor cells. It has been shown to induce colony formation of macrophages, neutrophils, mast cells and megakaryocytes from agar-suspended bone marrow cells.
