Co-treatment of ECO with MSC reduces radiation-induced colonic ulcers. Representative histological pictures of the colon in the different groups. Scale bars represent 200 µm. Quantification of the therapeutic benefit for the epithelial compartment of the colon in the different treated groups. Ulcer size was measured on histologic slides. Ulcers were pointed out by dark bars. Number of animals per group varied from n = 6 to n = 8. Results are expressed as mean ± SEM (*p < 0.05 versus IRR with Matrigel, **p < 0.01 versus IRR with Matrigel). IRR = Irradiated.
