Neurological diseases can significantly reduce the quality and duration of life. Stem cells provide a promising solution, not only due to their regenerative features but also for a variety of other functions, including reducing inflammation and promoting angiogenesis. Although only hematopoietic cells have been approved by the FDA so far, the number of trials continues to expand. We analyzed 492 clinical trials and illustrate the trends in stem cells origins, indications, and phase and status of the clinical trials. The most common neurological disorders treated with stem cells were injuries of brain, spinal cord, and peripheral nerves (14%), stroke (13%), multiple sclerosis (12%), and brain tumors (11%). Mesenchymal stem cells dominated (83%) although the choice of stem cells was highly dependent on the neurological disorder. Of the 492 trials, only two trials have reached phase 4, with most of all other trials being in phases 1 or 2, or transitioning between them (83%). Based on a comparison of the obtained results with similar works and further analysis of the literature, we discuss some of the challenges and future directions of stem cell therapies in the treatment of neurological diseases.
神经疾病会显著降低生活质量和缩短寿命。干细胞提供了一种有前景的解决方案,这不仅是因为它们的再生特性,还因为它们具有多种其他功能,包括减轻炎症和促进血管生成。尽管到目前为止,只有造血细胞被 FDA 批准,但临床试验的数量仍在不断增加。我们分析了 492 项临床试验,并说明了干细胞来源、适应症以及临床试验阶段和状态的趋势。用干细胞治疗的最常见的神经疾病是脑、脊髓和周围神经损伤(14%)、中风(13%)、多发性硬化症(12%)和脑肿瘤(11%)。间充质干细胞占主导地位(83%),尽管干细胞的选择高度依赖于神经疾病。在这 492 项试验中,只有两项试验已经进入第 4 阶段,而其他大多数试验处于第 1 或第 2 阶段,或在它们之间转换(83%)。基于与类似研究的结果比较,并对文献进行进一步分析,我们讨论了干细胞疗法在治疗神经疾病方面的一些挑战和未来方向。
