- aDMEM/F12 media containing antibiotics. Data are shown as mean extracellular matrix turnover marker concentration of all available supernatants of all incubated slices from all donors per group ± SD. C3M, PRO-C3 and FBN-C concentration was explored in (n) samples of 10 donors, PRO-C1 and PRO-C6 in (n) samples of 7 donors. Sufficient supernatant was not available to test all markers in some cases, so numbers vary. *P < 0.05 versus control. C3M, neo-epitope of MMP-9 mediated degradation of type III collagen; DMEM, Dulbecco’s modified Eagle’s medium/nutrient mixture; F-12, F-12 Ham; FBN-C, C-terminal of fibronectin; PCLS, precision-cut lung slices; PRO-C1 proteinase mediated release of the internal epitope in the N-terminal pro-peptide of type I collagen; PRO-C3, ADAMTS-2 mediated release of the N-terminal pro-peptide of type III collagen; PRO-C6, C-terminal of released C5 domain of type VI collagen α3 chain (endotrophin); SD, standard deviation; SEM, standard error of the mean
