微工程和组织工程结合的最新进展为实验医学和药学研究产生了有前途的微工程生理模型。在这里,我们回顾了微工程生理系统,或器官芯片,重建特定的人体组织和器官及其相互作用的生理关键特征的最新发展。该技术使用微工程方法来构建器官特异性微环境,重建组织结构,组织-组织相互作用和界面,以及在特定器官中发现的动态机械和生物化学刺激,以指导细胞组装成功能组织。我们首先讨论了微工程方法,以重现生理上重要的,动态的机械微环境,生化微环境,和微结构的微流控细胞培养系统中的特定组织和器官的关键要素。接下来是微工程个体器官模型的例子,这些模型将生理微环境的关键要素纳入单个微流体细胞培养系统,以再现器官水平的功能。最后,微工程多器官系统,模拟多器官的相互作用,以更好地代表人体生理学,包括人类对药物的反应,在这篇评论。这种新兴的器官芯片技术有可能成为2D和3D细胞培养和动物模型的替代品,用于实验医学,人类疾病建模,药物开发和毒理学。
Recent advances in integrating microengineering and tissue engineering have generated promising microengineered physiological models for experimental medicine and pharmaceutical research. Here we review the recent development of microengineered physiological systems, or organs on chips, that reconstitute the physiologically critical features of specific human tissues and organs and their interactions. This technology uses microengineering approaches to construct organ-specific microenvironments, reconstituting tissue structures, tissue–tissue interactions and interfaces, and dynamic mechanical and biochemical stimuli found in specific organs, to direct cells to assemble into functional tissues. We first discuss microengineering approaches to reproduce the key elements of physiologically important, dynamic mechanical microenvironments, biochemical microenvironments, and microarchitectures of specific tissues and organs in microfluidic cell culture systems. This is followed by examples of microengineered individual organ models that incorporate the key elements of physiological microenvironments into single microfluidic cell culture systems to reproduce organ-level functions. Finally, microengineered multiple organ systems that simulate multiple organ interactions to better represent human physiology, including human responses to drugs, is covered in this review. This emerging organs-on-chips technology has the potential to become an alternative to 2D and 3D cell culture and animal models for experimental medicine, human disease modeling, drug development, and toxicology.
