神经干细胞微环境在神经再生中的作用

Effect of neural stem cell niche in neurogenesis

  • 摘要: 神经干细胞是一类具有自我更新能力和多向分化潜能的细胞,在特定的条件下可以分化形成神经元、星形胶质细胞和少突胶质细胞。神经再生参与多种神经系统疾病的恢复,如脑卒中和阿尔茨海默病等。神经再生在成年哺乳动物脑内终身存在,主要包括神经干细胞的增殖、迁移、分化及新生神经元整合至神经环路4个阶段。神经干细胞的增殖分化等行为高度依赖于其生长的微环境,即神经干细胞微环境(niche)。神经干细胞niche主要包括:与神经干细胞相邻的支持细胞、细胞因子、细胞外基质和微血管网等。深入了解神经干细胞niche各组分对于神经再生的作用,对于临床神经系统疾病的治疗具有重要意义。本综述将对神经干细胞niche及其与神经干细胞命运调控的关系做简要概述。

     

    Abstract: Neural stem cell is a cell type with the ability of self-renewing and the potential to differentiate into neurons, astrocytes or oligodendrocytes. Neurogenesis is beneficial for the recovery of many neurological diseases, such as stroke, Alzheimer's disease and so on. Neurogenesis capacity can maintain through the whole life, which includes the proliferation, migration and differentiation of neural stem cell, as well as the incorporation into the neuronal network of newborn neurons. The self-renewal and differentiation activities of neural stem cell are regulated by the microenvironment, which is defined as neural stem cell niche. Components of neural stem cell niche include cell-cell interactions, cytokines, extracellular matrix and vascular niche. Illustration of neural stem cell niche impact is far more significant for the treatment of certain nervous system diseases. This review summarizes the current understanding of the relationship between neural stem cell niche and the fate of neural stem cell.
