摘要
类器官是源自人类干细胞、器官特异性祖细胞及分离肿瘤组织的自组装三维多细胞微型器官模型,可在体外重现器官的关键结构特征与生理机能。微流控芯片作为类器官的体外培养平台,为研究细胞在异质群体和微环境中的行为提供机会,因此,成为助力人类器官发育研究、疾病建模及药物筛选的强大工具。基于先进纳米技术构建的药物载体可以显著提升疾病治疗效果,是目前新药物研发和临床治疗的焦点。利用类器官芯片对纳米递送系统的安全性和有效性进行评估,不仅有助于了解药物递送载体与靶点微环境的相互作用机制,科学指导纳米载体的设计;也在患者个性化精准医疗领域具有应用价值。本文讨论了传统二维细胞模型以及动物模型评价纳米药物递送系统的局限性,分析了用类器官芯片作为体外评价平台的优势。在此基础上,总结了近年来类器官芯片在纳米药物递送领域的应用现状与发展方向,并对其前景进行了展望。
Organoids are self-assembling three-dimensional multicellular structures derived from human stem cells,organ-specific progenitor cells or isolated tumor tissues,which could reproduce the key structural features and physiological functions of organs in vitro.As an in vitro culture platform for organoids,microfluidic chips provide opportunities to study the behavior of cells in heterogeneous populations and microenvironments.Therefore,they have become a powerful tool to assist human organ development research,disease modeling,and drug screening.Nanomaterials,as an advanced carrier for drug delivery,can significantly improve the therapeutic effects of drugs and have become the focus of new drug development.Organoids-on-chip not only provide a reliable platform for evaluating the safety and efficacy of nano-drug delivery systems,but also help the design of nanocarriers and personalized treatment.In this review,we give an update on the limitations of traditional twodimensional cell models and animal models in nano-drug delivery systems evaluation,with an emphasis on the advantages of in vitro platforms by organoids-on-chip.It also summarized the recent application and development of organoids technology and future directions in nano-drug delivery systems.
