Outline of Final Research Achievements

We investigated the administration of adipose stem cells (ASCs) to improve the engraftment rate of transplanted fat in breast reconstruction using ASCs, hoping that additional administration of ASCs would improve angiogenesis, which contributes to fat engraftment. However, although additional administration of ASCs resulted in more angiogenesis than single administration of ASCs, inflammation was stronger and the rate of improvement in blood flow was worse. It was suggested that the additional administration may have induced inflammation and inhibited the effect of improving blood flow.

Academic Significance and Societal Importance of the Research Achievements

脂肪幹細胞(ASCs)を用いた乳房再建において、移植脂肪の生着率の向上のため、ASCsの投与方法とそのメカニズム解明を目的とした。移植脂肪生着に寄与するASCsの血管新生作用を持続させるため、下肢虚血モデルを用いてASCsの追加投与について検討したが、血管新生は認めるも血流改善の効果は得られず、炎症性作用の関与が示唆された。現在、多くの疾患に、ASCsの様々な作用が期待されて臨床適用されているが、疾患によって必要な作用が異なっている。ASCsの投与間隔や投与量による効果の差や、期待する特定の作用を強化する方法の開発の必要性を示した点で意義がある。
