Nanosilicates Promote Angiogenesis Through Activation of ROS-Mediated WNT/β-Catenin Pathway

GSE270943 Homo sapiens Expression profiling by high throughput sequencing 6 samples Submitted 2025/06/20 Platform GPL24676
Summary
Scaffold vascularization plays a pivotal role in the wound healing process, facilitating the recruitment of endogenous progenitor cells and delivering crucial signaling molecules that promote cellular invasion, angiogenesis, and neo-tissue formation. In this study, we introduce nanosilicates as pro-angiogenic biomaterials that can prime endogenous cells to expedite angiogenesis and graft vascularization in vivo. Characterized by their mineral-based two-dimensional (2D) structure and extensive surface area, nanosilicates are efficiently internalized by endothelial cells, leading to augmented cellular migration and the formation of tubular structures. Through whole transcriptome sequencing, we elucidated that nanosilicates activate the canonical Wnt pathway through hypoxia-induced ROS production. In vivo investigations further corroborate the pro-angiogenic efficacy of nanosilicates-loaded biomaterials. This study posits nanosilicates as a potential pro-angiogenic adjunct in the design of biomaterials for in situ tissue regeneration.
