Abstract
AbstractTissue-engineered constructs have immense potential as autologous grafts for wound healing. Despite the rapid advancement in fabrication technology, the major limitation is controlling angiogenesis within these constructs to form a vascular network. Here, we aimed to develop a 3D scaffold that can regulate angiogenesis. We tested the effect of fibronectin and vascular smooth muscle cells derived from human induced pluripotent stem cells (hiPSC-VSMC) on the morphogenesis of endothelial cells. The results demonstrate that fibronectin increases the number of endothelial networks. However, hiPSC-VSMC in the presence of fibronectin further substantiated the number and size of endothelial networks. A mechanistic study shows that blocking αvβ3 integrin signaling between hiPSC-VSMC and fibronectin impacts the endothelial network formation. Collectively, this study set forth initial design criteria in developing an improved pre-vascularized construct.
