TY - JOUR AB - Extracellular matrix (ECM) remodelling is integral to numerousphysiological and pathological processes in biology, such asembryogenesis, wound healing, fibrosis and cancer. Until recently,most cellular studies have been conducted on 2D environmentswhere mechanical cues significantly differ from physiologicallyrelevant 3D environments, impacting cellular behaviour andmasking the interpretation of cellular function in health and disease.We present an integrated methodology where cell-ECM interactionscan be investigated in 3D environments via ECM remodelling.Monitoring and quantification of collagen-I structure in remodelledmatrices, through designated algorithms, show that 3D matrices canbe used to correlate remodelling with increased ECM stiffnessobserved in fibrosis. Pancreatic stellate cells (PSCs) are the keyeffectors of the stromal fibrosis associated to pancreatic cancer. Weuse PSCs to implement our methodology and demonstrate that PSCmatrix remodelling capabilities depend on their contractile machineryand β1 integrin-mediated cell-ECM attachment.
