(A) Injection of UC-MSCs reduced pulmonary edema induced by LPS. Pulmonary edema was measured as the wet-dry ratio. (B): BALF protein concentration significantly increased after LPS injection and reached its peak at 24 h, while UC-MSCs caused a non-satistically significant decrease in the protein concentration. (*, p < 0.05 compared with healthy controls; #, p < 0.05 comparing LPS plus UC-MSCs with LPS alone.).
