中文摘要:
      目的 研究新型矿化胶原膜对MG-63人骨肉瘤细胞(简称:MG-63细胞)成骨分化相关基因表达的影响。方法 将MG-63细胞与新型矿化胶原膜浸提液(实验组)共培养,以市售的胶原膜(Bio-gide)浸提液作为同类产品对照组,以不加材料的细胞培养液为空白对照组,采用荧光实时定量PCR法检测碱性磷酸酶(ALP)、I型胶原(COL I)、骨保护素(OPG)和骨钙素(OC)mRNA表达水平;采用SPSS 17.0软件对数据进行统计学分析。结果 在ALP与OPG mRNA相对表达量检测中,3组成骨细胞的表达量差异无统计学意义(P> 0.05);在COL I与OC基因相对表达量检测中,14天时Bio-gide组和矿化胶原膜组表达均明显上调,与空白对照组相比,差异均具有统计学意义(P< 0.05),而Bio-gide组和矿化胶原膜组相比,差异无统计学意义(P> 0.05)。结论 矿化胶原膜和Bio-gide膜的浸提液均可上调MG-63细胞COL I和OC的基因表达,在一定程度上促进了成骨细胞的分化。
英文摘要:
      Objective The aim of this study was to observe the effects of a novel mineralized collagen membrane on the expression of genes associated with the differentiation of MG-63 osteosarcoma cell. Methods MG-63 Human Osteosarcoma cells were co-cultured with the extracts of the new mineralized collagen membrane (experimental group). The extracts of the commercially available collagen membrane (Bio-gide) was used as the control group of similar products, and the cell medium culture was used as a blank control group. RTPCR was used to detect alkaline phosphatase (ALP), collagen type I (Col I), osteoprotegerin (OPG) and osteocalcin (OC) mRNA expression levels. SPSS 17.0 software was used for statistical analysis of the data. Results There was no significant difference in the relative expression levels of ALP and OPG mRNA among the three groups (P> 0.05). The expression levels of OC and COL I at 14 day in the both membrane group was significantly upregulated compared with the blank control group (P< 0.05), while the Bio-gide group and the mineralized collagen membrane group had no statistically significant difference (P> 0.05). Conclusion The extracts of the mineralized collagen membrane and Bio-gide membrane can up-regulate the COL I and OC mRNA expression of MG63 cells and promote the differentiation of osteoblasts, at least to a certain degree.
