Outline of Final Research Achievements

Adipose derived stem cells (ADSCs) migrate on a micro patterned substrate quickly rather than other cells contained in adipose tissue. In this study, we developed the micro patterned substrate (Cell Migrating Separator) which can extract and cultivate ADSCs quickly from adipose tissue by using the character of ADSCs. The Cell Migrating Separator, which has a striped pattern structure, is an innovative micropatterned substrate that can rapidly extract and culture large amounts of ADSCs simply by seeding adipose tissue slices. This technology can be applied to extracting and culturing a variety of cells, including the safe extraction and culturing of iPS cells with a low risk of canceration.

Academic Significance and Societal Importance of the Research Achievements

我々は、安全で良質な細胞を迅速に大量生産できるシンプルなシステムを開発した。本システムはシンプルゆえに汎用性の高いシステムになる可能性を秘めており、ADSCsやiPS細胞だけでなく、様々な組織に含まれる細胞の抽出・培養や、疾患組織の細胞診断などにも応用可能である。そのため、医療産業への波及効果は非常に大きく、巨大な市場を新規開拓できると考えている。また、本システムは、遊走能の異なる細胞を的確に分離同定することが可能であることから、遊走能の異なる細胞の多様な細胞機能を厳密に評価するような基礎研究用のツールとしても有望だと考えられる。
