Glial cell line-derived neurotrophic factor improves impaired colonic motility in experimental colitis mice through connexin 43

Figure 4 Immunohistochemical staining and quantification of connexin 43 and glial cell line-derived neurotrophic factor in colonic tissues. A: Representative immunohistochemical images of connexin 43 and glial cell line-derived neurotrophic factor in colonic tissues (scale bar: 50 μm); B: Quantification of the mean optical density of connexin 43; C: Quantification of the mean optical density of glial cell line-derived neurotrophic factor staining. Data were presented as mean ± SD (n = 8). ^bP < 0.01. GDNF: Glial cell line-derived neurotrophic factor; UC: Ulcerative colitis; CN: Normal control; Cx43: Connexin 43.
