(A) BALF neutrophil counts and (B) lung MPO activity. Neutrophil counts and lung tissue MPO activity were significantly higher in the LPS group compared to the control group. Treatment with UC-MSCs significantly reduced the LPS-induced increase in BALF neutrophil counts and lung MPO activity at 24 and 48 hours (*, p < 0.05 compared with healthy controls; #, p < 0.05 comparing LPS plus UC-MSCs with LPS alone).
