Lung organoids in COPD: recent advances and future prospects

Area of Science:

• Pulmonary Medicine
• Regenerative Medicine
• Biotechnology

Background:

• Chronic obstructive pulmonary disease (COPD) is a major global health concern with high mortality.
• Current research models inadequately replicate human lung pathophysiology, hindering mechanistic understanding.
• Limitations in existing in vitro and animal models necessitate novel approaches for COPD research.

Purpose of the Study:

• To review the generation of lung organoids from various cell sources.
• To explore the application of lung organoids in chronic obstructive pulmonary disease (COPD) research.
• To suggest future research directions utilizing lung organoids for COPD.

Main Methods:

• Lung organoids are three-dimensional in vitro models derived from stem cells (adult, pluripotent, or embryonic).
• These models are cultured to mimic human lung structure and function.
• The review synthesizes data on organoid generation and their use in COPD studies.

Main Results:

• Lung organoids demonstrate high homology and genetic consistency with human lung tissues.
• They offer a more accurate representation of human lung structure and function compared to traditional models.
• Organoid systems provide a promising platform for investigating COPD mechanisms.

Conclusions:

• Lung organoids represent a significant advancement for in vitro modeling of human lung diseases like COPD.
• Their ability to recapitulate human lung physiology facilitates deeper insights into COPD pathogenesis.
• Further research utilizing lung organoids is crucial for developing effective COPD therapies.
