Outline of Final Research Achievements |
Although many studies have been performed about human vascular pathological conditions such as arteriosclerosis, the whole picture of the molecular mechanism is still unknown. In the present study, iPS cells were established from patients who developed vascular disorders due to congenital abnormalities, and vascular cells were induced from the iPS cells using the vascular differentiation method already established by ourselves. We performed differentiation and analysis of vascular cells using iPS cells established from patients with CADASIL or Takayasu disease with a family history.

Academic Significance and Societal Importance of the Research Achievements |
ヒトiPS細胞からの血管構成細胞の分化誘導法に関してはこれまでに我々の研究室以外からも複数の報告があるが、我々の誘導法は簡便で再現性も高く、また血管内皮細胞のみならず、血管壁細胞も誘導できるというメリットを持つ。この誘導法を用いて本研究ではCADASILと高安病という遺伝的素因が病態に関連している血管関連疾患に罹患した患者様から樹立したiPS細胞を用いて、血管細胞誘導および試験管内病態再現を目指して研究した。結果CADASIL-iPSを用いた研究につき、病態解明に繋がる病態再現に成功し、これを発表した。これら血管関連疾患の新規治療法に繋がる知見が得られることが期待できる成果である。
