T.Attorney, Agent or FirmInternational ClassesA61K 037/02A61K 037/36 AbstractActivin is administered systemically and locally to induce the growth of mature bone. Activin enhances the level of bone formation and the quality of the bone formed when administered locally with BMP or bone marrow. Administration of activin by subcutaneous route promotes systemic increase in the bone mass.Other References
