| Outline of Final Research Achievements |
Branching morphogenesis in lung is critical tissue morphogenesis to generate the epithelial tubular structures. Although Wnt signaling has been known to regulate lung branching morphogenesis, the role of Wnt signaling in the regulation of cellular function has been unclear. In this study, by using the cultured lung epithelium, I aim to study the cellular processes in branching morphogenesis regulated by Wnt signaling. I found that Wnt signaling regulates the apical cytoskeletal organization and apical-basal polarization, thereby modulating the bud formation by restricting the mitotic cell dependent tissue bending. This study proposes the concept and analytical methodology for cellular function regulated by the growth factor signaling pathways in tissue morphogenesis.
