Outline of Final Research Achievements |
This study aims to develop three-dimensional in vitro angiogenesis model on microdevice chip. The microvessels of several sizes (120, 200, and 300 micrometer in diameter) were successfully prepared and angiogenesis was induced by addition of vascular endothelial growth factor (VEGF). Angiogenesis induction was characterized by the sizes of the prepared microvasculatures. Longer and larger neovascular vessels formed from host microvasculature with smaller diameters, while only small sprouts were detected from large microvasculatures. By observation of the angiogenesis models, we visualized 3D features of the angiogenic sprouting process and provide information on the dynamics of luminal formation.
