Immunofluorescence staining of CS-exposed lung. Immunofluorescence staining was conducted to study the expression of a p65 (purple) and DAPI (turquoise) in the lung. b Percentage of p65 expression in all groups. p65 expression was increased when exposed to CS, and smoking cessation for 2 weeks significantly reduced the expression of p65. The expression of p65 was further reduced when treated with hUC-MSCs, hUC-MSC-EVs, and hUC-MSC-CM. *p < 0.05, **p < 0.01, ****p < 0.0001
