- Epigallocatechin gallate(EGCG), which is isolated from green tea, has been shown to have various pharmacological effects. In recent years, we have developed vacuum heated sponge material integrated with epigallocatechin gallate (vhEGCG-GS). Recently, vhEGCG-GS has been proven to have excellent bone regenerative ability. We examined the effects of EGCG on matrix metalloproteinase (MMP)-2 and MMP-9（gelatinases that disintegrate gelatin）expression in gelatin sponges and its association with bone formation. Four kinds of gelatin sponges with or without EGCG were prepared and implanted into bone defects for up to 4 weeks. Histological and immunohistological stainings were then performed. Micro-computed tomography was used to estimate the bone-forming capacity of each group. The results showed that EGCG integration attenuated MMP-2 and -9 expression, increased residual gelatin, and augmented bone formation in critical-sized bone defects of rat calvaria compared with vacuum-heated gelatin sponges without EGCG. In addition, vhEGCG showed superior bone formation compared with other sponges. The results indicated that integration of EGCG in gelatin-based materials modulated the production and activity of MMP-2 and -9 in vivo, thereby enhancing bone-forming capacity.2019年度機関リポジトリ記載の権利情報: CC BY-NC-ND
