| Outline of Final Research Achievements |
In this study, we developed two technologies, including in vivo angiogenesis induced in a spatially controlled manner (subject 1) and recruitment of angiogenic cells from cell tissue-like constructs (subject 2). In the subject 1, we demonstrated that the controlled release of angiogenic growth factors from biodegradable micro and/or nano particles could induce the in vivo angiogenesis. On the contrary, in the subject 2, we developed a stimuli-responsive material that allows vascular endothelial cells to be positioned into cell tissue-like constructs in an efficient and spatially controlled manner. The material can be fabricated in the desired shape, and vascular endothelial cells can attach on the surface of the material. Upon using the material with vascular endothelial cells, we fabricated cell tissue-like constructs with vascular-like structures.
