肺由40多种不同的细胞类型组成,支持高效肺功能所需的复杂三维(3D)结构。失去这种适当的结构可能会适应和促进肺部疾病,突显出研究人员越来越需要详细分析肺结构。此外,体内细胞和分子对化学和物理信号的反应,以及基因表达模式的重现,可能会在从复杂的3D组织向2D细胞培养系统的过渡过程中丢失。因此,需要能够利用整个肺结构来研究正常和疾病状态下的肺功能的技术,以产生对这些过程的完整理解。呼吸道细胞衍生的有机类化合物可以在体外重现肺的结构和功能,同时又可以进行实验操作,为肺生物学的研究提供了一个新的令人兴奋的模型系统。从这个角度,我们讨论了培养肺源性有机化合物的新兴技术,使用高分辨率显微镜可视化有机化合物的技术,以及从有机化合物中提取的信息,以支持专注于肺功能和疾病的研究。网上版载有补充材料,可在10.1007/s00418-020-01955-w查阅。
The lung is comprised of more than 40 distinct cell types that support a complex 3-dimensional (3D) architecture that is required for efficient lung function. Loss of this proper architecture can accommodate and promote lung disease, highlighting researchers’ growing need to analyze lung structures in detail. Additionally, in vivo cellular and molecular response to chemical and physical signals, along with the recapitulation of gene-expression patterns, can be lost during the transition from complex 3D tissues to 2D cell culture systems. Therefore, technologies that allow for the investigation of lung function under normal and disease states utilizing the entirety of the lung architecture are required to generate a complete understanding of these processes. Airway cell-derived organoids that can recapitulate lung structure and function ex vivo while being amenable to experimental manipulation, have provided a new and exciting model system to investigate lung biology. In this perspective, we discuss emerging technologies for culturing lung-derived organoids, techniques to visualize organoids using high-resolution microscopy and the resulting information extracted from organoids supporting research focused on lung function and diseases.
