文题释义:
骨形态发生蛋白2:
大量研究表明骨形态发生蛋白2可促进体外培养的间充质干细胞分化为成骨细胞,目前已被批准应用于临床以促进骨折愈合,就针对骨形态发生蛋白2在体内代谢过快的缺点,组织工程学中常用缓释载体包埋骨形态发生蛋白2,使其获得更好的生物学功效。
鼻黏膜来源的外胚间充质干细胞:为分布于头面部黏膜内的特殊类型的干细胞,来源于胚胎时期的神经嵴,该细胞仍保留多向分化潜能。鼻腔黏膜包括呼吸部黏膜和嗅部黏膜,关于嗅黏膜干细胞和嗅鞘细胞修复神经系统损伤的研究较多。

 

摘要
背景:
利用磷酸钙骨水泥载间充质干细胞治疗骨缺损已取得令人满意的成果,但是鼻黏膜来源的外胚层间充质干细胞与磷酸钙骨水泥的体外相容性尚不清楚。
目的:探讨磷酸钙骨水泥对大鼠鼻黏膜来源外胚间充质干细胞向成骨细胞分化的影响,进一步探讨鼻黏膜来源外胚间充质干细胞与磷酸钙骨水泥的生物相容性。
方法:体外培养扩增鼻黏膜来源外胚间充质干细胞,并将其种植于磷酸钙骨水泥表面和培养板(对照组),均进行成骨诱导14 d。碱性磷酸酶活性法检测鼻黏膜来源外胚间充质干细胞的碱性磷酸酶活性,茜素红染色法测定钙结节面积大小,免疫荧光和免疫印迹法检测成骨诱导相关蛋白表达水平;鬼笔环肽染色法动态观察磷酸钙骨水泥表面的细胞形态;MTT法检测磷酸钙骨水泥对细胞增殖的影响。
结果与结论:①成骨诱导14 d后,磷酸钙骨水泥表面的鼻黏膜来源外胚间充质干细胞碱性磷酸酶活性较高,形成的钙结节较大,骨相关蛋白表达水平较高;②磷酸钙骨水泥对鼻黏膜来源外胚间充质干细胞的增殖有一定的促进作用;③结果表明,鼻黏膜来源外胚间充质干细胞与磷酸钙骨水泥支架材料具有良好的生物相容性,磷酸钙骨水泥对鼻黏膜来源外胚间充质干细胞向成骨细胞分化表现出一定的促进作用。

Abstract:

BACKGROUND: The use of calcium phosphate cement (CPC) carrying mesenchymal stem cells for the treatment of bone defects has achieved satisfactory results. The in vitro compatibility of ectomesenchymal stem cells (EMSCs) derived from the nasal mucosa with CPC is unknown. 
OBJECTIVE: To investigate the effect of calcium phosphate cement on the differentiation of rat nasal mucosa-derived EMSCs into osteoblasts and to further explore the biocompatibility of EMSCs and CPC. 
METHODS: EMSCs were cultured, expanded in vitro and implanted onto the CPC surface or onto culture plates. Then, implanted EMSCs were induced to differentiate into osteoblasts for 14 days. Alkaline phosphatase activity assay was used to detect the alkaline phosphatase activity of EMSCs. The area of calcium nodules was determined by alizarin red staining. The expression level of osteogenesis-related proteins was detected by western blot assay and immunofluorescence method. Morphology of EMSCs on the CPC surface was dynamically observed using phalloidin staining. MTT assay was used to detect the proliferation of EMSCs on the CPC surface. 
RESULTS AND CONCLUSION: After 14 days of osteogenic induction, there was higher alkaline phosphatase activity, larger calcium nodules and higher levels of osteogenesis-related proteins in the EMSCs implanted on the surface of CPC than those implanted on the culture plates. The CPC had a certain role in promoting the proliferation of EMSCs. To conclude, EMSCs and CPC scaffolds have good biocompatibility, and moreover, CPC can certainly promote the differentiation of EMSCs into osteoblasts.
