A–F: Scratching associated hyperparakeratosis, epidermal thickening (hyperplasia) and looser upper dermis, (A: yellow arrows; E; N=3) are reduced after MGE-transplantation (B). Neither inflammatory infiltrate (A, B, E; N=3), nor mast cell number differed in control (C; N=3) and transplanted mice (D, F; N=4). Data: ± SEM; *** P<0.001; Student’s t-test. Scale bar: 145 μm.
