METHODS AND COMPOSITIONS FOR TREATING BONE DISEASES

摘要

The invention provides methods and compositions for stimulating or promoting bone generation and regeneration, for stimulating or increasing differentiation, activation or function of osteoblasts, for inhibiting or decreasing differentiation, activation or function of osteoclasts, and for treating bone diseases such as osteonecrosis by administering to a subject a therapeutically effective amount of a pro-nerve growth factor (proNGF) or a pro-brain derived neurotrophic factor (proBDNF) or an analog, homolog, fragment or derivative thereof. The pro-nerve growth factor (proNGF) or a pro-brain derived neurotrophic factor (proBDNF) or an analog, homolog, fragment or derivative thereof may be a mutated or poorly hydrolyzed form of proNGF or proBDNF.
