摘要: Background: Chinese hamster ovary (CHO) cell-derived recombinant human bone morphogenetic protein-2 (rhBMP-2) has been introduced for spine, long bone, and craniofacial indications. Escherichia coli- (E. coli) derived rhBMP-2 displays comparable efficacy to CHO in vitro small-animal models. The objective of this study is evaluate the E. coli-derived compared benchmark using an established large-animal model.Methods: Contralateral, critical-size supraalveolar peri-implant defects six adult male Hound Labrador mongrel dogs received cell- or (0.2 mg/mL) absorbable collagen sponge (ACS) carrier. In each quadrant, three dental implants were placed. A titanium mesh device was used support space provision. animals fluorescent markers qualitative evaluations. Animals euthanized at 8 weeks histopathologic histometric evaluation.Results: Clinical healing inclu...
