Effect of PDLSCs’ transplantation on macrophage polarization and cytokine secretion. The immunochemistry staining against CD163, CD206, iNOS, TNF-α, and IL-10 on day 3 (a), day 7 (c), and day 21 (e) after surgery. Quantification of the number of iNOS+ cells, the number of CD163+ cells and CD206+ cells, and the positive area of TNF-α and IL-10 in the field was performed on day 3 (b), day 7 (d), and day 21 (f) after surgery. *p < 0.05
