Effects of full-length ECM proteins on ASCs. (A) Proliferation on different substrates was quantified (*p < 0.05) (B) Secretion of adipogenic factors (adiponectin and leptin) by ASCs cultured on different ECM proteins was quantified by ELISA at day 1 (dark bars) and day 14 (light bars). Secretion of bFGF and SDF1- α (C) and VEGF and HGF (D) by ASCs cultured on different ECM proteins was quantified by ELISA over time (***p < 0.001; **p < 0.01; *p < 0.05). bFGF, basic fibroblast growth factor; Col I, collagen I; Col IV, collagen IV; FN, fibronectin; HGF, hepatocyte growth factor; LM, Laminin; SDF-1α, stromal cell-derived factor 1α; VEGF, vascular endothelial growth factor; VN, vitronectin.
