    摘要: A protein is provided derived from human fibroblast having an N-terminal amino acid sequence represented by SEQ ID NOS: 1 and 2, having a molecular weight of approximately 15kD under reducing and non-reducing conditions by (dosium dodecyl sulfate-polyacrylamide gel electrophoresis), and having an activity to stimulate growth of osteoblast. The protein is produced by gene engineering procedures, contains the amino acid sequence represented by SEQ ID NO: 9 and has osteoblast growth activity. Also provided is a method for preparing the protein by culturing human fibroblast and treating the conditioned medium for purification. The protein is utilized for the treatment of diseases characterized by decreased bone mass such as osteoporosis or is utilized as an antigen for immunological diagnosis of diseases.
