Outline of Final Research Achievements

Tissue regeneration with autologous somatic stem cells has attracted attention as one of the regenerative therapy. Adipose tissue can be harvested by low invasive procedure because of its location. Moreover, adipose tissue includes 500 to 1000 times of stem cells than bone marrow. In this study, we focused on adipose-derived stem cells (ASC) as a source of somatic stem cells, and evaluated its differentiatin potential for osteoblastic cells by three-dimentional culture and/or co-culture with monocyte-macrophage lineages. We further evaluated the effect of bisphosphonates for osteogenesis of ASC and other stem cells harvested from oral cavity and bone marrow stem cells. Furthermore, we compared the characteristics and proliferation/differentiation ability between ASCs isolated from abdominal fat tissue and buccal fat pad. Our results suggested that ASCs isolated from buccal fat pad has a possibility to generate a novel autologous tissue graft by using monocyte-macrophage lineages.

Academic Significance and Societal Importance of the Research Achievements

体性幹細胞は様々な組織に潜在的に含まれているが、特に脂肪由来由来幹細胞は上皮直下の脂肪組織中に存在しており、採取が低侵襲であることと、幹細胞の含有量が骨髄に比較して約 1000 倍であることから注目されている。また、自己の組織であることと、遺伝子導入を必要としない点にもメリットがあると考えられている。我々は脂肪組織の採取部位によってその中に含まれる脂肪由来幹細胞の性質が異なることを確認した。また、単球-マクロファージ系と共存することや、ビスフォスフォネート製剤の添加により、骨芽細胞分化が促進されることも明らかにした。これらの方法が確立できれば、低侵襲に採取可能な自己組織移植材として使用できる。
