<p>Methods and compositions for using conjugates of bone growth factors and targeting molecules in bone repair and augmentation are provided. The bone growth factor and targeting molecule are chemically conjugated to a crosslinker. The crosslinker is preferably a synthetic hydrophilic polymer. The bone growth factor is preferably TGF-β, activin, or bone morphogenic protein (BMP). Targeting molecules preferably have an affinity for bone, such as tetracycline, calcein, bisphosphonate, polyaspartic acid, polyglutamic acid, aminophosphosugars, or estrogen.</p> |
