| Outline of Final Research Achievements |
Lymphangiogenesis is involved in many pathophysiology; cancer metastasis, inflammation and lymphedema. In this study, we carried out examination of lymphangiogenesis in tail dermis after birth using mouse model. The specific deletion of FoxO1 in endothelial cells lead to impaired formation of lymphatic vessel network through defects in migration and proliferation of endothelial cells. Moreover, we identified CXCR4 as a candidate of causative gene of this defective phenotype, which was most significantly decreased by reduction of FOXO1 in lymphatic endothelial cells. These findings suggested that Foxo1 and target genes play important roles in lymphangiogenesis.
