Immunohistochemistry staining of NF-κB: positive cells with the PLLA scaffold (a–d) and with the PLLA/ACP scaffold (e–h). Note the significantly lower expression of NF-κB 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.)
