成人大脑皮层长期以来被认为是非神经源性的。损伤是否能诱导成年皮层神经发生仍有争议。在这里,我们报告说,局灶性缺血刺激局部神经发生的瞬态波。用5′-溴-2 ′-脱氧尿苷标记,我们证明了双皮质素阳性神经母细胞的快速产生,在小鼠大脑皮层缺血后迅速死亡。基于Nestin-CreER的细胞消融和命运映射显示室管膜下区神经干细胞对成神经细胞的贡献很小。利用一个小的光血栓缺血小鼠模型和逆转录病毒表达的绿色荧光蛋白标记,我们观察到本地产生的新神经元的成熟。此外,使用PDGFRα-、GFAP-和Sox 2-CreER小鼠的命运追踪分析显示,轻度缺血皮质中神经母细胞生成的瞬时波,并确定Sox 2阳性星形胶质细胞是成年皮质中的主要神经源性细胞。此外,在猕猴局灶性缺血皮质中观察到类似的Sox 2上调和成神经细胞的出现。我们的研究结果表明,在缺血性皮质Sox 2阳性星形胶质细胞的短暂神经源性反应,这表明在未来通过放大这种内在反应诱导神经元再生的可能性。
The adult cortex has long been regarded as non-neurogenic. Whether injury can induce neurogenesis in the adult cortex is still controversial. Here, we report that focal ischemia stimulates a transient wave of local neurogenesis. Using 5′-bromo-2′-deoxyuridine labeling, we demonstrated a rapid generation of doublecortin-positive neuroblasts that died quickly in mouse cerebral cortex following ischemia. Nestin-CreER-based cell ablation and fate mapping showed a small contribution of neuroblasts by subventricular zone neural stem cells. Using a mini-photothrombotic ischemia mouse model and retrovirus expressing green fluorescent protein labeling, we observed maturation of locally generated new neurons. Furthermore, fate tracing analyses using PDGFRα-, GFAP-, and Sox2-CreER mice showed a transient wave of neuroblast generation in mild ischemic cortex and identified that Sox2-positive astrocytes were the major neurogenic cells in adult cortex. In addition, a similar upregulation of Sox2 and appearance of neuroblasts were observed in the focal ischemic cortex of Macaca mulatta. Our findings demonstrated a transient neurogenic response of Sox2-positive astrocytes in ischemic cortex, which suggests the possibility of inducing neuronal regeneration by amplifying this intrinsic response in the future.
