Precision-Cut Lung Slices: Emerging Tools for Preclinical and Translational Lung Research: An Official American...

The urgent need for effective treatments for acute and chronic lung diseases underscores the significance of developing innovative preclinical human research tools. The 2023 American Thoracic Society Workshop on Precision-Cut Lung Slices (PCLSs) brought together 35 experts to discuss and address the role of human tissue-derived PCLSs as a unique tool for target and drug discovery and validation in pulmonary medicine. With increasing interest and usage, together with advancements in methods and technology, there is a growing need for consensus on PCLS methodology and readouts. The current document recommends standard reporting criteria and emphasizes the requirement for careful collection and integration of clinical metadata. We further discuss current clinically relevant readouts that can be applied to PCLSs and highlight recent developments and future steps for implementing novel technologies for PCLS modeling and analysis. The collection and correlation of clinical metadata and multiomic analysis will further advance the integration of this preclinical platform into patient endotyping and the development of tailored therapies for patients with lung disease.
