α/β integrin expression of (A) HCFs and (B) NHLFs cultured on cardiac ECM, lung ECM, and individual ECM components (coll, type 1 collagen; FN, fibronectin; LECM1, lung ECM; CECM2, cardiac ECM derived from second condition—see text for details). *The set of conditions are statistically different from each other as shown by analysis of variance (ANOVA, p<0.05). Error bars represent mean±SD. Color images available online at www.liebertpub.com/tea
