釉基质蛋白(EMP)可促进牙周膜细胞(PDLC)的增殖和多向分化能力。在EMP的作用下,PDLC中与合成细胞外基质功能相关的基因表达提高,PDLC的矿化和碱性磷酸酶(AKP)活性提高。EMP可促进骨髓基质干细胞(BMSC)成骨向分化,上调其成骨相关基因的表达,BMSC中的AKP活性提高。EMP通过上调连接蛋白-43和神经钙黏着蛋白等细胞间交流黏附因子增强成骨细胞分化。EMP可促进未成熟的成骨细胞聚集,这种聚集对连接蛋白-43和神经钙黏着蛋白上调有重要的作用,进一步提高了成骨细胞的分化和矿化活性。EMP可促进牙骨质形成,促进上皮细胞的增殖、活性和迁移。明确EMP的作用机制并利用机制调控产物,可为牙周组织缺损的临床治疗提供新的依据。
釉基質蛋白(EMP)可促進牙週膜細胞(PDLC)的增殖和多嚮分化能力。在EMP的作用下,PDLC中與閤成細胞外基質功能相關的基因錶達提高,PDLC的礦化和堿性燐痠酶(AKP)活性提高。EMP可促進骨髓基質榦細胞(BMSC)成骨嚮分化,上調其成骨相關基因的錶達,BMSC中的AKP活性提高。EMP通過上調連接蛋白-43和神經鈣黏著蛋白等細胞間交流黏附因子增彊成骨細胞分化。EMP可促進未成熟的成骨細胞聚集,這種聚集對連接蛋白-43和神經鈣黏著蛋白上調有重要的作用,進一步提高瞭成骨細胞的分化和礦化活性。EMP可促進牙骨質形成,促進上皮細胞的增殖、活性和遷移。明確EMP的作用機製併利用機製調控產物,可為牙週組織缺損的臨床治療提供新的依據。
