目的:观察釉基质蛋白(enamel matrix proteins,EMPs)对牙龈间充质干细胞(human gingival mesenchymal stem cells,hGMSCs)增殖和Ⅰ型胶原合成的影响。方法:分离培养人牙龈成纤维细胞,免疫细胞化学方法检测其间充质干细胞特性STRO-1的表达,不同浓度EMPs,25 mg/L(A1组)、50 mg/L(A2组)、100 mg/L(A3组)、200 mg/L(A4组),对照组(A0组)10%FCS的DMEM溶液培养,MTT检测EMPs对细胞增殖活性的影响。免疫细胞化学方法鉴定细胞Ⅰ型胶原合成和图像分析。结果:50~200mg/L表现出促hGMSCs增殖的作用,50 mg/L EMPs即可以显著促进hGMSCs的生长,但以100 mg/L EMPs的促增殖作用最强(与其余各组相比P<0.01),实验组胶原合成明显强于对照组。其中,100mg/L促 I型胶原(collagen typeⅠ,COLⅠ—合成最明显,且随时间变化。结论:EMP可促进hGMSCs增殖和Ⅰ型胶原合成。
目的:觀察釉基質蛋白(enamel matrix proteins,EMPs)對牙齦間充質榦細胞(human gingival mesenchymal stem cells,hGMSCs)增殖和Ⅰ型膠原閤成的影響。方法:分離培養人牙齦成纖維細胞,免疫細胞化學方法檢測其間充質榦細胞特性STRO-1的錶達,不同濃度EMPs,25 mg/L(A1組)、50 mg/L(A2組)、100 mg/L(A3組)、200 mg/L(A4組),對照組(A0組)10%FCS的DMEM溶液培養,MTT檢測EMPs對細胞增殖活性的影響。免疫細胞化學方法鑒定細胞Ⅰ型膠原閤成和圖像分析。結果:50~200mg/L錶現齣促hGMSCs增殖的作用,50 mg/L EMPs即可以顯著促進hGMSCs的生長,但以100 mg/L EMPs的促增殖作用最彊(與其餘各組相比P<0.01),實驗組膠原閤成明顯彊于對照組。其中,100mg/L促 I型膠原(collagen typeⅠ,COLⅠ—閤成最明顯,且隨時間變化。結論:EMP可促進hGMSCs增殖和Ⅰ型膠原閤成。

Objective To assess the effects of enamel matrix proteins on proliferation and type I colla?gen synthesis of human gingival mesenchymal stem cells(hGMSCs). Methods The primary gingival fi?broblasts were cultured and then mesenchymal stem cell surface markers STRO-1 were characterized by Immunocytochemistry.hGMSCs was cultured in concentrations of enamel matrix protein 25 mg/L (A1 group),50 mg/L (A2 group),100 mg/L (A3 group),200 mg/L (groupA4),control group (group A0) DMEM solution of 2%FCS training,The cell proliferation was detected by MTT. Immunocytochemistry and image analysis of type I collagen synthesis. Results 50-200mg/L showed hGMSCs proliferation promoting effect,50 mg/L EMPs that can significantly promote the growth of hGMSCs,but to promote proliferation of the strongest 100 mg/L EMPs.(Compared with other groups,P<0.01) in experimental group was better than control group,collagen synthesis.Among them,the most obvious 100mg/L pro?mote the synthesis of collagen type I,and changing with time. Conclusion The enamel matrix protein can promote the proliferation of hGMSCs and type I collagen synthesis.
