“…The level of gene expression in the surrounding tissue to regenerate bone can be enhanced by delivery of plasmid DNA using hydrogel microspheres, more than plasmid DNA solution. BMP 2 -incorporated gelatin/ β-TCP scaffolds lead to significantly increased osteogenesis compared to the chem- ical induced osteogenesis in specimens [60,65,66,68,70,75,76,78,92,[98][99][100]109,[116][117][118][119][120][121]. In previous studies, various groups showed a continuous release of BMP2 in vitro and in vivo [65,66,68,70,73,75,76,92,[98][99][100]109,[119][120][121].…”
