Spongy-like hydrogels prevascularization with the adipose tissue vascular fract...
Moreira, Helena R.; Rodrigues, Daniel Barreira; Ribeiro, Sara Freitas; Silva, Lucília Pereira; Morais, Alain da S.; Jarnalo, Mariana; Horta, RicardoIn vitro prevascularization is one of the most explored approaches to foster engineered tissue vascularization. We previously demonstrated a benefit in tissue neovascularization by using integrin-specific biomaterials prevascularized by stromal vascular fraction (SVF) cells, which triggered vasculogenesis in the absence of extrinsic growth factors. SVF cells are also associated to biological processes important...
Integrin-specific hydrogels for growth factor-free vasculogenesis
Moreira, Helena R.; Rodrigues, Daniel Barreira; Ribeiro, Sara Freitas; Silva, Lucília Pereira; Morais, Alain da S.; Jarnalo, Mariana; Horta, RicardoIntegrin-binding biomaterials have been extensively evaluated for their capacity to enable de novo formation of capillary-like structures/vessels, ultimately supporting neovascularization in vivo. Yet, the role of integrins as vascular initiators in engineered materials is still not well understood. Here, we show that αvβ3 integrin-specific 3D matrices were able to retain PECAM1+ cells from the stromal vascu...
