中风仍然是西方世界残疾的主要原因。尽管经过几十年的研究,目前还没有临床上有效的治疗方法来促进中风的康复。干细胞可能具有减少损伤和促进中风后恢复的潜力。在动物模型中,移植的干细胞已被证明可迁移到受伤区域,分泌神经营养化合物,促进血管再生,增强可塑性并调节炎症反应,从而最大限度地减少损伤。内源性神经干细胞也具有对损伤做出反应的显著倾向。在选定的条件下,室管膜下区祖细胞可以动员,以取代失去的神经元。在对局灶性梗死的反应中,成神经细胞发挥重要的营养作用以使神经损伤最小化。重要的是,这些内源性修复机制可以通过实验增强,从而导致功能的稳健改善。目前正在进行的临床研究正在评估基于细胞的治疗中风的安全性和可行性。我们概述了中风干细胞研究临床转化的独特挑战和潜在陷阱。然后,我们详细介绍了我们认为克服这些挑战所需的具体基础科学和临床策略,填补了知识的空白,并促进了临床可行的基于干细胞的中风疗法的发展。
Stroke remains the leading cause of disability in the Western world. Despite decades of work, no clinically effective therapies exist to facilitate recovery from stroke. Stem cells may have the potential to minimize injury and promote recovery after stroke. Transplanted stem cells have been shown in animal models to migrate to the injured region, secrete neurotrophic compounds, promote revascularization, enhance plasticity and regulate the inflammatory response, thereby minimizing injury. Endogenous neural stem cells also have a remarkable propensity to respond to injury. Under select conditions, subventricular zone progenitors may be mobilized to replace lost neurons. In response to focal infarcts, neuroblasts play important trophic roles to minimize neural injury. Importantly, these endogenous repair mechanisms may be experimentally augmented, leading to robust improvements in function. Ongoing clinical studies are now assessing the safety and feasibility of cell-based therapies for stroke. We outline the unique challenges and potential pitfalls in the clinical translation of stem cell research for stroke. We then detail what we believe to be the specific basic science and clinical strategies needed to overcome these challenges, fill remaining gaps in knowledge and facilitate development of clinically viable stem cell-based therapies for stroke.
