Preparation of rh-BMP-2 loaded chitosan microsphere and its properties in vitro / 中国矫形外科杂志

ABSTRACT

85%).From the in vitro release experiment,the rhBMP-2 was controlled to release from the chitosan microsphere over 30 days.[Conclusion]The rhBMP-2 loaded chitosan microsphere prepared by emulsion cross-linking method shows a good controlled release property.Such a novel type of controlled release system has the potential of being applied for controlled cytokine delivery and the bone tissue engineering.
