[ECTOPIC OSTEOGENESIS EVALUATION OF RECOMBINANT HUMAN BONE MORPHOGENETIC PROTEIN 2 LOADED CHITOSAN/DEXTRAN SULFATE BY MICRO-CT].

OBJECTIVE To evaluate the ectopic osteogenesis of recombinant human bone morphogenetic protein 2 (rhBMP-2) loaded chitosan (CS)/dextran sulfate (DS) by micro-CT.rhBMP-2/CS/DS microspheres were prepared by the ionic crosslinking and its shape was observed under the scanning electron microscope. The release of rhBMP-2 was determined from resultant microspheres by ELISA assay. Forty-eight Sprague Dawley male rats were randomly divided into 4 groups...
