Author is Di Caprio, Nikolas; Bellas, Evangelia.
Adipose tissue (AT) has a dynamic extracellular matrix (ECM) surrounding adipocytes that allows for remodeling during metabolic fluctuations. During the progression of obesity, AT has increased ECM deposition, stiffening, and remodeling, resulting in a pro-fibrotic dysfunctional state. Here, the incorporation of ethylene glycol-bis-succinic acid N-hydroxysuccinimide ester (PEGDS) allows for control over 3D collagen hydrogel stiffness and architecture to investigate its influence on adipocyte metabolic and fibrotic function. Upon stiffening and altering ECM architecture, adipocytes did not alter their expression of key adipokines, leptin, and adiponectin. However, they do increase actin cytoskeletal fiber formation, pro-fibrotic gene expression, ECM deposition, and remodeling within a stiffer, 3D collagen hydrogel. For example, COL6A3 gene expression is upregulated approx. twofold, resulting in increased deposition of pericellular collagen VI alpha 3 surrounding adipocytes. Furthermore, inhibition of actin contractility results in a reversal of pro-fibrotic gene expression and ECM deposition, indicating that adipocytes are mediating mech. cues through actin cytoskeletal networks. This study demonstrates that ECM stiffness and architecture plays a critical regulatory role in adipocyte fibrotic function and contributes to the overall pro-fibrotic dysfunctional state of AT during the progression of obesity and AT fibrosis.
