(B) The representative images of Haematoxylin and eosin (H&E) staining and the thickness of epidermis were measured. (C) The representative images of toluidine blue staining and the mast cell number were counted. Data were expressed as mean ± SEM. ### p < 0.001, compared with the blank group; ** p < 0.01, *** p < 0.001, compared with the AEW model group (n = 3 each group).
