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

<div>Immunohistochemistry staining of MMP-9: positive cells with the PLLA scaffold (a–d) and with the PLLA/ACP scaffold (e–h). Note the significantly lower expression of MMP-9 in the PLLA/ACP stented artery (e–h) compared with that of the PLLA stented artery (a–d). (The red arrows show positive cells. ×200.)</div>
