Adipocyte fibrosis
WebSep 9, 2024 · Adipose tissue fibrosis identifies unhealthy remodeling in obesity Unresolved inflammation is often associated with altered tissue remodeling in a number of pathological states and often progresses to fibrosis as a result of the persistence of inflammatory stress. WebOct 4, 2024 · Adipose tissue fibrosis has multiple potential effects on adipocytes. By providing a rigid ECM, fibrosis may prevent excessive enlargement of adipocytes. Fibrosis may exert shear stress on the adipocyte membrane, opposing the mechanical stress exerted by enlarged lipid droplets within the cell.
