SDF-1α mRNA therapy in peripheral artery disease.

ABSTRACT: Stromal cell-derived factor-1 alpha (SDF-1α) is a promising target for therapeutic angiogenesis in ischemic diseases such as peripheral artery disease (PAD). However, the clinical application of SDF-1α protein or plasmid-based gene therapy is unsuccessful. mRNA therapy has shown great promise in protein replacement. Here, we developed DOPE-lipid nanoparticles (LNPs) encapsulating SDF-1α mRNA (LNP@SDF-1α) for efficient gene delivery. In vitro, LNP@SDF-1α treatment of human umbilical vein endothelial cells (HUVECs) significantly enhanced endothelial migration, tube formation, and increased monocyte adhesion, demonstrating robust pro-angiogenic activity. In vivo, LNP@SDF-1α transfected HUVECs showed enhanced angiogenic capacity in a murine Matrigel plug model. Furthermore, in a mouse hindlimb
