Abstract: Induction of angiogenesis has enormous potential in the treatment of ischemic diseases and
the promotion of bulk tissue regeneration. However, the poor activity of angiogenic cells and proangiogenic
factors after transplantation is the main problem that imposes its wide applications. Recent
studies have found that the development of nanomaterials has solved this problem to some extent.
Nanomaterials can be mainly classified into inorganic nanomaterials represented by metals, metal oxides
and metal hydroxides, and organic nanomaterials including DNA tetrahedrons, graphene, graphene
oxide, and carbon nanotubes. These nanomaterials can induce the release of angiogenic factors
either directly or indirectly, thereby initiating a series of signaling pathways to induce angiogenesis.
Moreover, appropriate surface modifications of nanomaterial facilitate a variety of functions, such as
enhancing its biocompatibility and biostability. In clinical applications, nanomaterials can promote the
proliferation and differentiation of endothelial cells or mesenchymal stem cells, thereby promoting the
migration of hemangioblast cells to form new blood vessels. This review outlines the role of nanomaterials
in angiogenesis and is intended to provide new insights into the clinical treatment of systemic
and ischemic diseases.
