Vascular extracellular matrix in the media consists of elastin, proteoglycans and fibrillar collagen. With the provision of flexibility by elastin, and biomechanical strength by fibrillar collagen, the arterial vessel is able to maintain the structural integrity despite the high pressure within the lumen. Fibrillar collagen can also inhibit the proliferation of smooth muscle cell in vitro according to recent evidence. The matrix also plays a role in the process of cellular responses to stimuli, such as growth factors and may for example deter the cells to undergo apoptosis.
