Outline of Final Research Achievements

Vascular endothelial progenitor cells are one of important cell populations to play pivotal roles in angiogenesis and wound healing. In this study, we developed a purification method of adipose derived endothelial progenitor cell (AEPC) from human lipoaspirates. Expanded AEPC was performed characterization and functional analysis in comparison with human umbilical vein endothelial cell (HUVEC). AEPC was comparable to HUVEC in colony forming unit capacity, tube formation capacity, and expression profile of endothelial cell markers.

Academic Significance and Societal Importance of the Research Achievements

学術的意義:血管系の研究分野では、それぞれの組織から調製した血管内皮細胞・前駆細胞に対する研究がなされている。ヒト脂肪組織に存在するAEPCは、これまで純化培養法が確立されていなかったために基礎的データの蓄積ができなかったが、今回、AEPCの純化培養に成功したことにより、データ取得が可能な段階になった。本研究では、AEPCの血管内皮細胞としての性質、前駆細胞としての性質に関する細胞特性解析を行い、新規の知見を提供できた。社会的意義:純化AEPC/AECを獲得できたことにより、再生医療の新たな候補ツールを得ることが出来た。
