成年哺乳动物脊髓脑室-室下区的神经干细胞(NSC)可能对修复脊髓损伤大有裨益。然而,NSCs 的来源仍不清楚。此前,我们已经证实脑脊液接触神经元(CSF-cN)在体外具有 NSC 潜力。在这项研究中,我们验证了 CSF-cNs 体内的 NSC 特性。在小鼠脊髓中,位于中央管周围的 Pkd2l1+ CSF-cN 表达 NSC 标记。在体外,Pkd2l1+ CSF-cN 形成神经球并表达 NSC 标记。通过向侧脑室注射神经营养因子碱性成纤维细胞生长因子(bFGF)和血管内皮生长因子(VEGF)可以诱导CSF-cNs的激活和增殖。脊髓损伤 (SCI) 还会诱导 NSC 活化和 CSF-cN 增殖。总的来说,我们的结果表明 Pkd2l1+ CSF-cN 在体内具有 NSC 特性,并且可能参与 SCI 恢复。
The neural stem cells (NSCs) in the ventricular-subventricular zone of the adult mammalian spinal cord may be of great benefit for repairing spinal cord injuries. However, the sources of NSCs remain unclear. Previously, we have confirmed that cerebrospinal fluid-contacting neurons (CSF-cNs) have NSC potential in vitro. In this study, we verified the NSC properties of CSF-cNs in vivo. In mouse spinal cords, Pkd2l1+ CSF-cNs localized around the central canal express NSC markers. In vitro, Pkd2l1+ CSF-cNs form a neurosphere and express NSC markers. Activation and proliferation of CSF-cNs can be induced by injection of the neurotrophic factors basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF) into the lateral ventricle. Spinal cord injury (SCI) also induces NSC activation and proliferation of CSF-cNs. Collectively, our results demonstrate that Pkd2l1+ CSF-cNs have NSC properties in vivo and may be involved in SCI recovery.
