血管化脑类器官的技术进展与应用前景

The Technological Advances and Prospects of Vascularized Brain Organoids

  • 摘要: 脑血管病具有高发病率、高致残率和高死亡率的特点,已成为全球范围内导致死亡和长期残疾的主要原因之一。类器官技术作为一种基于干细胞或组织细胞体外培养的微型器官模型,能够模拟器官的发育、生理和病理过程,在脑血管疾病研究与治疗方面展现出广阔前景。本文阐述了类器官技术在脑血管疾病领域的最新应用进展,重点探讨了血管化脑类器官的构建策略,包括体内移植、体外培养及生物工程技术。研究发现,这些模型不仅能够还原神经血管单元的相互作用,还在药物筛选和疾病机制探究方面发挥重要作用,为脑血管疾病的治疗提供了新策略。与此同时,类器官技术亦面临诸如血管化效率不足、与宿主组织整合能力有限等挑战。未来,结合基因编辑、微流控芯片和高通量3D打印等技术,有望进一步提升血管化脑类器官的功能性与临床可用性,为个性化治疗及精准医疗提供新方向。

     

    Abstract: Cerebrovascular diseases, characterized by high incidence, disability, and mortality rates, have emerged as a leading global cause of death and long-term disability. Organoid technology, a three-dimensional in vitro culture system derived from stem cells or tissue cells, enables the simulation of organ development, physiological processes, and pathological mechanisms, demonstrating significant potential in cerebrovascular disease research and therapeutic development. This review summarizes recent advances in organoid applications for cerebrovascular diseases, with a focus on strategies for constructing vascularized cerebral organoids, including in vivo transplantation, in vitro culture systems, and bioengineering approaches. Studies reveal that these models not only recapitulate neurovascular unit interactions but also serve as powerful platforms for drug screening and mechanistic investigations, offering novel therapeutic strategies for cerebrovascular disorders. Current challenges include insufficient vascularization efficiency and limited integration capacity with host tissues. Future integration of gene editing, microfluidic chips, and high-throughput 3D bioprinting technologies is expected to enhance the functionality and clinical translatability of vascularized cerebral organoids, thereby advancing personalized medicine and precision healthcare.
