Human pluripotent stem cell-derived lung organoids: Potential applications in development and disease modeling

Area of Science:

• Pulmonary Medicine
• Stem Cell Biology
• Regenerative Medicine

Background:

• Traditional 2D in vitro systems and animal models have limitations in accurately recapitulating human lung complexity and cell interactions.
• Primary human cell sources for lung modeling are often limited in availability and accessibility.

Purpose of the Study:

• To review the advantages and limitations of human pluripotent stem cell (hPSC)-derived lung models.
• To explore the potential of 2D and 3D lung models, particularly lung organoids, for studying lung development and diseases.
• To discuss current and future applications of these advanced models.

Main Methods:

• Review of protocols for differentiating hPSCs towards pulmonary lineages in vitro.
• Analysis of 2D and 3D lung models derived from hPSCs.
• Focus on lung organoids as a cutting-edge model system.

Main Results:

• hPSC-derived lung models, including 3D organoids, provide a more accurate representation of the human lung environment and cell crosstalk.
• Lung organoids are currently the most advanced model for mimicking the human pulmonary system.
• These models show significant potential for studying complex lung diseases.

Conclusions:

• hPSC-derived lung organoids represent a powerful tool for understanding lung development and pathogenesis.
• Applications include modeling pulmonary fibrosis, infectious diseases, and lung cancer.
• Further development of these 3D models holds promise for future therapeutic strategies.
