One of the monocytic cell colony stimulating factors produced by thymic myoid cells, a 100 kDa factor, was purified by reversed phase HPLC and found to be homologous to the secreted form of proteoglycan 1 (biglycan) core protein. This biglycan associated colony stimulating factor did not carry an immunological motif of macrophage colony stimulating factor (M-CSF), but predominantly stimulated the proliferation and differentiation of monocytic lineage cells from bone marrow cells, nonadherent thymic cells and peritoneal exudate cells.
