Porous gelatin/tricalcium phosphate/genipin composites containing lumbrokinase for bone repair
2015
Abstract Bone cell activities are very important in bone remodeling. This study investigates the effects of lumbrokinase on bone cell activities in cultures. Moreover, a biodegradable composite (GGT) containing genipin-crosslinked gelatin and β-tricalcium phosphate was prepared to carry lumbrokinase (GGTLK). Rat calvarial bone defects were filled with GGT and GGTLK composites. Bone healing was monitored in vivo by bioluminescence imaging and micro-CT. Lumbrokinase was found to have a dose-dependent effect on bone cell activities. Low concentrations (
