Immunohistochemical staining of macrophage polarization markers CD206 (M2, anti-inflammatory) and iNOS (M1, pro-inflammatory) in the repaired tendons. AC Immunohistochemistry with CD206 antibody. DF Immunohistochemistry with iNOS antibody. The upper right panels indicate the images of lower magnifications. G The percentage of CD206 positive cells. H The percentage of iNOS positive cells. R group, random silk scaffold alone. A group, aligned silk scaffold alone. AC group, hPDLSCs seeded aligned silk scaffold. *p < 0.05; ****p < 0.0001
