Title:	Methods for promoting growth of bone, ligament, and cartilage
Abstract:	Methods for promoting growth of bone, ligament, or cartilage in a mammal are disclosed. The methods comprise administering to said mammal a composition comprising a pharmacologically effective amount of a zvegf3 protein in combination with a pharmaceutically acceptable delivery vehicle. Also disclosed are methods for promoting proliferation or differentiation of osteoblasts, osteoclasts, chondrocytes, or bone marrow stem cells comprising culturing the cells in an effective amount of a zvegf3 protein.

Application Number:	11/552,848
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 dimeric protein comprising a first polypeptide chain disulfide bonded to a second polypeptide chain, each of said chains consisting of an amino acid sequence having at least 95% sequence identity with residues 235-345 of SEQ ID NO:2, wherein said dimeric protein is capable of binding PDGF receptor .alpha.; and 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 wherein the bony defect is a fracture, bone graft site, 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 composition is locally administered at a joint. 7. The method of claim 1 wherein the dimeric protein is covalently linked to a bone-targeting agent. 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, a fibroblast growth factor, and a protein comprising residues 258-370 of SEQ ID NO:5.
