Effects of MSC treatment on histological changes and body weight in colitis. Colonic structure assessed via haematoxylin and eosin staining of cross sections from tissues collected at 24 h a-d and 72 h a′-d′ post TNBS administration. Scale bar = 50 μm. e Body weight recorded at 24, 48 and 72 h after TNBS administration and expressed as the change from baseline measurements. *p < 0.05, **p < 0.01, ***p < 0.001, n = 4 animals/group/time point.
