Abstract

The extracellular matrix (ECM) is constantly remodeling in response to various extracellular and intracellular stimuli, and the way in which these signals are transmitted, captured and interpreted by cells, determines and differentiates the fate of normal or pathological remodeling. Response to stimuli is a hallmark of the definition of life. Communication between cells is essential and is profoundly influenced by the ECM. In this context, the ECM and its remodeling, as well as the interactions between its different components constitute a research area at the frontier of knowledge. The present proposal encompasses three main approaches: 1) Systematic characterization of the structure of glycosaminoglycans and proteoglycans of the matrix and cell surface; 2) Study of ECM functions using biological models in vitro, in vivo and ex vivo; 3) Cell response to ECM variations. A methodological arsenal involving state-of-the-art techniques from glycobiology, cellular, molecular and structural biology, bioengineering and translational science will be used to respond to these hypotheses.
