EZH2 Might Affect Macrophage Chemotaxis and Anti-Inflammatory Factors by Regulating CCL2 in Dental Pulp Inflammation

Figure 1

The effects of LPS on dental pulp tissue and TNF-α expression. (a) Hematoxylin-eosin analyses of nontreated pulp (control) and experimental rat pulpitis induced by LPS treatment observed after 2 hours, 8 hours, 1 day, 3 days, and 7 days. Higher magnifications are shown in boxed areas. Scale bar: 200 μm in low magnifications and 50 μm in higher magnifications. (b) Immunohistochemical analyses of TNF-α expression of dental pulp with or without LPS treatment after 8 hours, 1 day, 3 days, and 7 days. Scale bar: 100 μm in low magnifications and 50 μm in higher magnifications ().
