【摘要】 目的:总结近年来交感神经及其递质影响、调控造血干细胞的相关研究,为造血干细胞的进一步研究、应用等提供参考。方法:广泛查阅交感神经系统与造血干细胞关系的研究文献,总结交感神经系统调控造血干细胞的方式、机制等。结果:交感神经及其神经递质对造血干细胞存在的微环境/壁龛、动员、增殖、衰老、损伤保护、昼夜节律等存在多位点的影响和调控。结论:交感神经及其递质对造血干细胞的调控相关研究主要集中在壁龛和动员的影响,需要进一步明确其机制、方式、阶段,为贫血、血液肿瘤等相关疾病治疗、造血干细胞临床应用等提供可靠的支持。

Progress of Research on the Relationship between Sympathetic Nervous System and Hematopoietic Stem Cells/ZHENG Kai, CHEN Chao, YUAN Shiguo. //Chinese and Foreign Medical Research, 2020, 18(17): -188

[Abstract] Objective: To summarize the related researches of hematopoietic stem cells (HSCs) regulated by sympathetic nervous system (SNS) or its transmitters, and to provide view for further research and application about stem cells. Method: The literatures on the relationship between SNS or its transmitters and HSCs were extensively reviewed, and the mechanisms of regulation were summarized. Result: The SNS or its transmitters multiple regulates the niche, mobilization, proliferation, senescence, injury protection, circadian rhythm, etc. of HSCs. Conclusion: The researches about regulation of SNS and its transmitters on HSCs mainly focuse on the influence of niche and mobilization. It is necessary to further clarify the mechanism, mode and stage for the treatment of anemia, hematological and other related diseases, and the clinical application of HSCs.

造血干細胞(haematopoietic stem cells,HSCs)从胚胎造血内皮细胞发育而来,并在胎儿肝脏中增殖,然后定居于骨髓中,具有自我复制、多向分化和重建长期造血的能力[1-2]。HSCs是目前研究最久远、最深入的干细胞[3-4]。HSCs可以在整个生命周期中自我更新,同时补充所有血系细胞,使HSCs移植成为治疗多种血液疾病、挽救生命的手段[5]。但是,临床上由于缺乏HLA匹配的骨髓供体和脐带血中HSCs的低产量限制了可治疗患者的人数[6]。更好地了解HSCs的调节机制以便培养扩增HSCs和产生多潜能干细胞[1,4,7]。目前研究发现,交感神经系统(sympathetic nervous system,SNS)及其神经递质对HSCs的壁龛、增殖、动员入血、自我更新等存在多靶点、多阶段的调控作用。本文拟综述SNS及其神经递质对HSC的调控作用及机制,为进一步研究、临床使用HSC提供参考。……
