Evaluation of deposited collagen in the repaired tendons. A–F Polarized light examination of repaired tissues with different magnifications. G–I Immunohistochemical staining of COL I in the repaired tendons. The upper right panels indicate the images of lower magnifications. J The percentage of COL I positive area. K Integrated optical density (IOD) values. R group, random silk scaffold alone. A group, aligned silk scaffold alone. AC group, hPDLSCs seeded aligned silk scaffold. *p < 0.05; ***p < 0.001; ****p < 0.0001
