Correlations between the expression of uPAR or mesenchymal marker vimentin positive cells in small airways and functional parameters. (A) The expression of uPAR in small airways of 78 subjects was correlated with FEV1% of predicted, as an index of airflow obstruction severity in COPD. (B) Mesenchymal marker vimentin positive cells per mm in small airways was correlated with FEV1% of predicted. (C) The expression of uPAR in small airways was correlated with vimentin positive cells per mm.
