제목 | Hydrogel with microtubular hollow structures for microvascularperfusion in ischemic model |
초록 | While angiogenesis is the key factor to treatischemic disease, angiogenesis induction such as local treatment withpro-angiogenic molecules has critical side effects including inflammatorycoupling, tumorous vascular activation, and off-target circulation. Here, astructural angiogenic induction is applied to physically engineerthree-dimensional channel networks in ischemic region. Microchannel networksare generated in a gelatin hydrogel to overcome the diffusion limit ofnutrients and oxygen three-dimensionally. Hydrogel implantation in mouse andporcine models of hindlimb ischemia rescues severely damaged tissues by theingrowth of neighboring host vessels with microchannel perfusion, mediated bysize-specific regenerative macrophage polarization. |
