摘要
少突胶质细胞(oligodendrocytes, OLs)是中枢神经系统(central nervous system, CNS)中主要的成髓鞘细胞,其功能障碍会引发一系列的神经性疾病,例如:多发性硬化症(multiple sclerosis,MS)和脑白质营养不良。少突胶质细胞祖细胞(oligodendrocyte precursor cells, OPCs)的移植是治疗髓鞘相关疾病的一种潜在方法。在脑损伤后, OPCs可向OLs方向分化并对损伤部位的轴突进行髓鞘化,但是, OPCs在大脑中仅占5%~8%,这种髓鞘修复作用十分有限。通过体外重编程技术生成诱导性少突胶质细胞祖细胞(induced oligodendrocyte precursor cells, iOPCs)的策略可为髓鞘损伤疾病的治疗提供大量的细胞资源。但是该方法仍存在一系列亟待解决的问题,包括i OPCs生成效率较低、体外培养周期较长等。因此,该文从限定性转录因子、miRNA以及小分子物质等方面阐述了iOPCs的生成方法,并分析了iOPCs的现存问题和应用前景,旨在为其在疾病模型构建、药物开发和再生医学等方面的应用提供理论和技术参考。
Oligodendrocytes(OLs) are the major type of myelin-generatingcells in the central nervous system(CNS), dysfunction of them contributes to a variety of neurological diseases, such as multiple sclerosis(MS) and congenital leukodystrophies. Transplantation of oligodendrocyte precursor cells(OPCs) is a promising therapeutic strategy for those demyelinating diseases. After the brain tissue is injured, OPCs will be differentiated into OLs which can remyelinate the axon, but this kind of repairability is very limited because there are only 5% to 8% OPCs in the brain. Reprogramming of mammalian cells into induced OPCs(iOPCs) in vitro is a promising strategy for remyelination, but some problems such as lower productive efficiency and long-time culture for generation of them in vitro need to be solved or improved. Therefore, different induced factors(including defined transcription factors, miRNAs and small molecules), problems and application prospects of iOPCs were reviewed in this paper in order to provide the theoretical and technological guidances for disease modeling, new drug development and regenerative medicine research.
