Myostatin inhibitor enhancement of musculoskeletal repair

摘要

The methods and compositions of this invention provide a means of regenerating injured musculoskeletal tissue by inhibition of myostatin function. The invention provides methods of treating a nonunion fracture in an individual comprising delivering to the fracture via a delivery system comprising biodegradable hydrogel, a pharmacological amount of myostatin propeptide effective to inhibit myostatin function. The invention also teaches compositions useful for the treatment of non-union fracture in an individual, said compositions comprising a pharmacological amount of myostatin propeptide effective to inhibit myostatin function; and a delivery system for delivering said myostatin propeptide to said fracture, wherein the delivery system comprises a biodegradable hydrogel or biodegradable nanobeads.
