Herbs-partitioned moxibustion alleviates aberrant intestinal epithelial cell apoptosis by upregulating A20 expression in a mouse model of Crohn’s disease

Figure 1 Histological observation of intestinal epithelial tissues across groups (magnification, ×100). A: Wild-type mice in normal control group; B: Wild-type mice in model control group; C: Wild-type mice in mesalazine group; D: Wild-type mice in herbs-partitioned moxibustion group; E: A20^IEC-KO mice in normal control group; F: A20^IEC-KO mice in model control group; G: A20^IEC-KO mice in mesalazine group; H: A20^IEC-KO mice in herbs-partitioned moxibustion group. 1: Tissue edema; 2: Hyperemia; 3: Inflammatory cell infiltration; 4: Necrosis; 5: Granulation tissue proliferation; 6: Destruction of glandular structure; 7: Healing ulcer; 8: Ulcer; 9: Proliferation of fibrous tissue.
