Extracellular matrix in aging aorta
WebAug 1, 2024 · Large, elastic arteries are composed of cells and a specialized extracellular matrix that provides reversible elasticity and strength. Elastin is the matrix protein responsible for this reversible elasticity that reduces the workload on the heart and dampens pulsatile flow in distal arteries. WebFeb 21, 2024 · SMC senescence increases with age in the normal-sized ascending aorta To assess for cellular senescence in the aortic media, we immunostained for the cell cycle inhibitors, p16 and p21. We found co-labeling of p16 and p21 in a small but significant portion of ascending aortas (15%).
