Role of Extracellular Matrix on Adipocyte Phenotype
The extracellular matrix (ECM) is an insoluble network of fibrous proteins and polysaccharides that not only serves as a source of cell attachment and mechanical support, but also provides a potent source of signaling through interactions with cell receptors and by acting as a reservoir of signaling molecules. Changes in the ECM often accompany pathologies. For instance, in obesity, which affects >650 million people worldwide, hypertrophic adipocytes secrete pro-inflammatory cytokines, which recruit macrophages. Chronic adipose tissue inflammation can induce fibrosis (increased ECM deposition) and contributes to a higher risk for conditions such as type 2 diabetes, coronary heart disease, stroke, and osteoarthritis. Although clear and distinct changes occur in the ECM during disease progression, the bulk of research has focused on methods for directly modulating cell-cell interactions. However, recent studies underscore the potency of the ECM as a therapeutic target. We are using a reductive approach that uses an engineered materials system to identify key extracellular matrix components and properties that contribute to adipocyte phenotype.
