Evaluation of Long-Term Inflammatory Responses after Implantation of a Novel Fully Bioabsorbable Scaffold Composed of Poly-L-lactic Acid and Amorphous Calcium Phosphate Nanoparticles
Western Blotting analysis of coronary arteries treated with PLLA scaffolds and PLLA/ACP scaffolds for 24 months. The expression of IL-1 in the PLLA/ACP group was significantly lower than that in the PLLA group at 12 months and 24 months (a and c). The expression of IL-6 in the PLLA/ACP group was significantly lower than that in the PLLA group at 6 months, 12 months, and 24 months (b and d). means the PLLA/ACP group compared with the PLLA group.
