Outline of Final Research Achievements

The field of lung development lags behind other tissues because of the complex tissue structure. The fact that Nrf2 could contribute to activation of lung developmental genes made us to analyze the relationship between Nrf2 (anti-oxidative stress gene) and lung development. In vivo lung regeneration experiment revealed that Nrf2 plays important roles in lung development. Given this, we next conducted in vitro studies using mouse pluripotent stem cells. Our results indicate that Nrf2 participates in lung development. Further studies are needed to apply this result to clinical use.
