Release of bioactive BMP from dextran-derived microspheres: A
novel delivery concept
A novel class of Dex-GMA microspheres were designed and synthesized by polymerization of Dex-GMA emulsified in an aqueous poly(ethylene glycol)(PEG) solution. Dex-GMA was prepared by substituting the hydroxyl groups in Dex by GMA. The drug loading and in vitro drug release was evaluated by routine procedure and the biological activity of BMP-loaded microspheres was studied by experimenta...
