Abstract

Human microphysiological systems, such as organs on chips, are an emerging technology for modeling human physiology in a preclinical setting to understand the mechanism of action of drugs, to evaluate the efficacy of treatment options for human disease and impairment, and to assess drug toxicity. By using human cells co-cultured in three-dimensional constructs, organ chips can provide greater fidelity to the human cellular condition than their two-dimensional predecessors. However, with the rise of SARS-CoV-2 and the global COVID-19 pandemic, it became clear that many microphysiological systems were not compatible with or optimized for studies of infectious disease and operation in a Biosafety Level 3 (BSL-3) environment. Given that one of the early sites of SARS-CoV-2 infection is the airway, we created a human airway organ chip that could operate in a BSL-3 space with high throughput and minimal manipulation, while retaining the necessary physical and physiological components to recapitulate tissue response to infectious agents and the immune response to infection.

摘要

人体微生理系统,如芯片上的器官,是一种新兴技术,用于在临床前环境中模拟人体生理,以了解药物的作用机制,评估人类疾病和损伤治疗方案的疗效,并评估药物毒性。通过使用在三维结构中共同培养的人类细胞,芯片上的器官比其二维前身能更真实地模拟人体细胞状况。然而,随着严重急性呼吸综合征冠状病毒2(SARS-CoV-2)的出现和全球新冠肺炎大流行,很明显,许多微生理系统与传染病研究不兼容,也未针对生物安全3级(BSL-3)环境下的操作进行优化。鉴于SARS-CoV-2感染的早期部位之一是气道,我们创建了一种人体气道芯片,它可以在BSL-3空间中以高通量和最少的操作运行,同时保留重现组织对感染因子的反应和对感染的免疫反应所需的物理和生理成分。
