Repairing damaged lungs using regenerative therapy

Abstract

There is an urgent need for better treatment of lung diseases that are a major cause of morbidity and mortality worldwide. This urgency is illustrated by the current COVID-19 health crisis. Moderate-to-extensive lung injury characterizes several lung diseases, and not only therapies that reduce such lung injury are needed but also those that regenerate lung tissue and repair existing lung injury. At present, such therapies are not available, but as a result of a rapid increase in our understanding of lung development and repair, lung regenerative therapies are on the horizon. Here, we discuss existing targets for treatment, as well as novel strategies for development of pharmacological and cell therapy-based regenerative treatment for a variety of lung diseases and clinical studies. We discuss how both patient-relevant in vitro disease models using innovative culture techniques and other advanced new technologies aid in the development of pulmonary regenerative medicine.

Approaches to drug discovery in pulmonary regenerative medicine. In vitro, in vivo, exvivo, and in silico modeling of respiratory lung diseases may be used for target identification as well as serve as the model to test drug efficacy. Thus, these complementary approaches contribute to development of new drug candidates, and these can be used in (semi) high-throughput screening approaches (depending on the technique). Such screening approaches are also particularly worthwhile for drug repurposing. Candidate drugs selected using such screens can be further analyzed and validated using the abovementioned in vivo, in vitro, and in silico approaches and lead to regenerative pulmonary medicine for a variety of lung diseases.

Regenerative approaches for lung diseases and the role of disease state. Lung diseases present with heterogenous characteristics, which emphasizes the need to consider different treatment approaches and combinations for pulmonary regenerative medicine. In addition, the choice for a therapy may be determined by the stage of the disease. ARDS, COPD, and fibrosis are presented as examples of diseases that may benefit from a regenerative therapy approach. See text for further details.
