Abstract
ABSTRACT Among deaths related to cardiovascular disease (CVD), arteriosclerosis accounts for three-quarters of the total. The most common treatment for arteriosclerosis is revascularization through the implantation of endovascular scaffolds. However, most metal scaffolds currently available are non-biodegradable, which can lead to rejection reactions. In this study, we have developed a CMCS-PEI/miR polysaccharide nucleic acid nanodrug loaded with miR-199a-5p for the first time. The CMCS-PEI/miR polysaccharide nucleic acid nanodrug exhibits good blood compatibility, successfully transfects cells, and induces apoptosis of vascular endothelial cells. Additionally, PCL/GO composite scaffolds with excellent mechanical properties and biocompatibility were fabricated using 3D printing technology. This technology allows for the customisation of scaffolds to meet the needs of individual patients. The 3D-printed PCL/GO composite scaffolds loaded with CMCS-PEI/miRNA polysaccharide nucleic acid nanodrug effectively induce apoptosis of vascular endothelial cells, showing great potential in promoting the functional repair of arteriosclerosis and preventing vascular restenosis.
