Title: Preparation of csf by transplantation of csf-producing tumor
Inventor: HIRASHIMA KUNITAKE
IPC: A61P37/00
Filed: 1981-10-03
Abstract: PURPOSE:USF(Colony Stimulating Factor)-producing tumor cells generated spontaneously in a C3H mouse are transplanted to another C3H mouse, and CSF is separated from the urine of the mouse. CONSTITUTION:CSF-producing tumor cells (e.g. cells originated from guanulosisinducing fibrocarcinoma) are transplanted to a C3H mouse, and CSF[a substance acting to myeloplast cells (CFU-C) and accelerating the differentiation and proliferation of the cell to granulocytes or macrophages]is separated form the urine of the transplanted mouse. CSF is a factor necessary for the formation of a colony by the differentiation and the simultaneous proliferation of CTU-C in the in vitro cultivation of myeloplast cells. The CSF acting to the human myeloid cell is expensive because it is necessary to use expensive human serum in the conventional preparation of CSF, however, the raw materials for the preparation of CSF in the present invention can be produced by mouse without necessitating expensive serum, etc., and accordingly CSF can be prepared in  bulk.
