Fig. 3From: Mesenchymal stem cells and acellular products attenuate murine induced colitisRepresentative histopathologic image findings of the colonic mucosa (H&E). Mucosa of the PBS control group (a), MSCs (b), and EVs (c); arrows mark the infiltration of inflammatory cells and nearly total loss of crypts at colonic mucosa of the PBS group. Mice had markedly reduced leukocyte infiltration in MSC and EV groups as assessed by H&E staining (magnification: upper, × 100; arrows shown at lower, × 200). d Histological damage score was calculated based on microscopic colonic epithelial damage and infiltration of inflammatory cells, and the microscopic damage score of the PBS group was significantly higher than that of MSC- and EV-treated groups. Data are represented as mean ± SEM, *p < 0.05Back to article page
