星形胶质细胞是中枢神经系统(CNS)中含量最丰富的细胞群,对于正常的神经功能是必不可少的。我们发现,星形胶质细胞在小鼠脊髓和脑中的空间域是根据它们在脑室区域的胚胎起源位置而分配的。这些结构域在整个生命过程中保持稳定,即使在急性中枢神经系统损伤后也没有第二次切向迁移的证据。脊髓腹侧区星形胶质细胞的区域特异性耗竭导致运动神经元突触形成异常,这不能通过邻近区域的星形胶质细胞迁移来挽救。我们的研究结果表明,星形胶质细胞的区域限制性分配是一种普遍的中枢神经系统现象,揭示了星形胶质细胞对损伤的反应的内在局限性。
Astrocytes, the most abundant cell population in the central nervous system (CNS), are essential for normal neurological function. We show that astrocytes are allocated to spatial domains in mouse spinal cord and brain in accordance with their embryonic sites of origin in the ventricular zone. These domains remain stable throughout life without evidence of secondary tangential migration, even after acute CNS injury. Domain-specific depletion of astrocytes in ventral spinal cord resulted in abnormal motor neuron synaptogenesis, which was not rescued by immigration of astrocytes from adjoining regions. Our findings demonstrate that region-restricted astrocyte allocation is a general CNS phenomenon and reveal intrinsic limitations of the astroglial response to injury.
