Self-assembled peptide-based nanofibers for cardiovascular tissue regeneration

Cardiovascular diseases are the leading cause of death worldwide, claiming millions of lives every year. Cardiac tissue engineering has emerged as a versatile option for repairing cardiac tissue and helping its regeneration. The use of nanomaterials, particularly nanofiber-based scaffolds combined with biomolecular cues like peptides, has significantly improved the compatibility and efficacy of the scaffolds for cardiac tissue regeneration. By utilising the self-assembly properties of peptides to create nanofiber scaffolds, we can achieve stability that closely mimics the natural components of cardiac tissue, making them perfect for cardiac tissue regeneration. In this review, we highlighted the dynamic process of self-assembly into nanofibers and the use of various self-assembled nanofibers for cardiovascular tissue regeneration, focusing on their roles in antithrombotic, angiogenic, differentiation, proliferation, and anti-atherosclerotic interventions.
