Outline of Final Research Achievements |
As a treatment for lymphedema, conservative treatment and surgical treatment including lymphaticovenous anastomosis are performed, but treatment is often difficult. Therefore, effective treatment for lymphedema including new lymphatic regeneration is desired. It has been reported that VEGF-C which is one of vascular endothelial cell growth factors induces lymphatic regeneration in lymphedema tissues by stimulating lymphatic endothelium and promoting migration of lymphatic endothelial cells . In this study, we aimed to develop efficient treatment of lymphedema, and aimed to analyze the role played by VEGF-C in lymphedema tissue and factors related to the regulation of expression of VEGF-C in edematous tissue. It was demonstrated that the expression of inflammatory cells such as macrophages and hypoxia response factors such as HIF-1 alpha were increased in the lymphedema.
