Bone tissue engineering is the most promising technology for enhancing bone regeneration. Scaffolds loaded with osteogenic factors improve the therapeutic effect. In this study, the bioactive PEI (polyethylenimine)/pBMP2- (bone morphogenetic protein-2 plasmid-) PLGA (poly(D, L-lactic-co-glycolic acid)) core-shell scaffolds were prepared using coaxial… (More)

—This paper introduces the theory of assembly line balance and researches the production system and assembly line balance emulation issues. The method is to establish the assembly operation tree, give the constraint of assembly operation, rebuild the emulation model over and over and combine assembly process. In conclusion, this paper can help the… (More)
