Recent progress of stem cell biology gives us the hope for neural repair. We have established methods to specifically induce functional Schwann cells and neurons from bone marrow stromal cells (MSCs). The effectiveness of these induced cells was evaluated by grafting them either into peripheral nerve injury, spinal cord injury, or Parkinson' s disease animal models. MSCs-derived Schwann cells supported axonal regeneration and re-constructed myelin to facilitate the functional recovery in peripheral and spinal cord injury. MSCs-derived dopaminergic neurons integrated into host striatum and contributed to behavioral repair. In this review, we introduce the differentiation potential of MSCs and finally discuss about their benefits and drawbacks of these induction systems for cell-based therapy in neuro-traumatic and neuro-degenerative diseases.
干细胞生物学的最新进展给我们带来了神经修复的希望。我们已经建立了从骨髓基质细胞(MSCs)中特异性诱导功能性雪旺细胞和神经元的方法。通过将这些诱导细胞移植到周围神经损伤、脊髓损伤或帕金森病动物模型中,评估了这些诱导细胞的有效性。源自MSCs的雪旺细胞支持轴突再生并重建髓鞘,以促进周围神经和脊髓损伤后的功能恢复。源自MSCs的多巴胺能神经元整合到宿主纹状体中,并有助于行为修复。在这篇综述中,我们介绍了MSCs的分化潜能,并最终讨论了这些诱导系统在神经创伤和神经退行性疾病的细胞治疗中的优缺点。
