| Outline of Final Research Achievements |
Irradiated human adipose tissue-derived stem cells (ADSC) have been found to promote cell proliferation, migration and luminogenesis of human cutaneous lymphatic endothelial cells. Irradiation promotes the secretion of basic fibroblast growth factor from ADSC, and is thought to activate vascular endothelial growth factor-C, which is considered to be the most important factor in promoting lymphatic endothelial cell proliferation and lymphangiogenesis.

| Academic Significance and Societal Importance of the Research Achievements |
本研究により、ヒト脂肪組織由来幹細胞はヒト皮膚リンパ管内皮細胞の細胞増殖能、遊走能および管腔形成能を促進し、さらにヒト脂肪組織由来幹細胞に放射線を照射すると効果がより高くなることが分かった。
放射線治療による四肢の二次性リンパ浮腫に対してヒト脂肪組織由来幹細胞が予防や治療に対して有効である可能性が示唆された。
