Application Number:10/910,938
Patent Claims:1. A method for promoting growth of bone, ligament, or cartilage in a mammal comprising administering to said mammal a composition comprising a pharmacologically effective amount of a protein comprising a first polypeptide disulfide-bonded to a second polpeptide, wherein each of said first and second polypeptides comprises amino acid residues 258 370 of SEQ ID NO:2 and wherein said protein is mitogenic or chemotactic for mesenchymal cells, in combination with a pharmaceutically acceptable delivery vehicle.

2. The method of claim 1 wherein the delivery vehicle is powdered bone, tricalcium phosphate, hydroxyapatite, polymethacrylate, a biodegradable polyester, an aqueous polymeric gel, or a fibrin sealant.

3. The method of claim 1 wherein the composition is locally administered at a site of a bony defect.

4. The method of claim 3 werein the bony defect is a fracture, bone graft size, implant site, or periodontal pocket.

5. The method of claim 1 wherein the composition is administered systemically.

6. The method of claim 1 wherein the protein is covalently linked to a bone targeting agent.

7. The method of claim 1 wherein the composition is locally administered at a joint.

8. The method of claim 1 wherein the composition further comprises a protein selected from the group consisting of insulin-like growth factor 1, platelet-derived growth factor, epidermal growth factor, transforming growth factor-alpha, transforming growth factor-beta, a bone morphogenetic protein, parathyroid hormone, osteoprotegerin, or a fibroblast growth factor.

9. The method of claim 1 wherein each of said first and second polypeptides comprises residues 250 370 of SEQ ID NO:2.

10. The method of claim 1 wherein each of said first and second polypeptides consists of residues 250 370 of SEQ ID NO:2.
