MSC‐preconditioned lung restricts infection‐induced inflammation and allows for better bacterial elimination. Three days after MSC infusion, mice were infected and sacrificed at the indicated time. (a) Scheme of the experiment. (b) Bacterial loads in the lung. (c) BALF cytokine levels. (d) Representative photographs of H&E staining. (e) Inflammation score. n = 4 each group; UD, undetected. ns, no significant difference. All the experiments were repeated three times, and representative data are shown.
