Spinal cord injuries (SCIs) are debilitating conditions for which no effective treatment currently exists. The damage of neural tissue causes disruption of neural tracts and neuron loss in the spinal cord. Stem cell replacement offers a solution for SCI treatment by providing a source of therapeutic cells for neural function restoration. Induced pluripotent stem cells (iPSCs) have been investigated as a potential type of stem cell for such therapies. Transplantation of iPSCs has been shown to be effective in restoring function after SCIs in animal models while they circumvent ethical and immunological concerns produced by other stem cell types. Another approach for the treatment of SCI involves the graft of a bioscaffold at the site of injury to create a microenvironment that enhances cellular viability and guides the growing axons. Studies suggest that a combination of these two treatment methods could have a synergistic effect on functional recovery post-neural injury. While much progress has been made, more research is needed before clinical trials are possible. This review highlights recent advancements using iPSCs and bioscaffolds for treatment of SCI.
脊髓损伤(SCI)是一种使人衰弱的病症,目前尚无有效的治疗方法。神经组织的损伤会导致脊髓中的神经束中断和神经元丢失。干细胞替代疗法通过提供用于恢复神经功能的治疗细胞来源,为脊髓损伤的治疗提供了一种解决方案。诱导多能干细胞(iPSC)已被研究作为此类疗法的一种潜在干细胞类型。在动物模型中,iPSC移植已被证明在脊髓损伤后恢复功能方面是有效的,同时它规避了其他干细胞类型所产生的伦理和免疫问题。另一种治疗脊髓损伤的方法是在损伤部位植入生物支架,以创建一个增强细胞活力并引导轴突生长的微环境。研究表明,这两种治疗方法的结合可能对神经损伤后的功能恢复产生协同作用。虽然已经取得了很大进展,但在进行临床试验之前还需要更多的研究。本综述重点介绍了使用iPSC和生物支架治疗脊髓损伤的最新进展。
