Vascular smooth muscle cell

Contraction and action potential of smooth muscle

The major cells in the media layer of arteries, vascular smooth muscle cells (VSMCs), are important for maintaining the arterial wall’s integrity. They are involved in arterial wall remodeling and play a significant role in the development of atherosclerosis. According to studies, VSMCs may take on a variety of phenotypes based on inputs from intima endothelial cells (ECs), adventitia resident cells, circulating immune cells, hormones, and plasma lipoproteins. They can perform several tasks in physiology and disease because of their plasticity. In this minireview, we focus on VSMCs’ role in atherosclerosis immunity through the formation of artery tertiary lymphoid organs, which was previously underappreciated (ATLOs).
1st Figure VSMC phenotypes show remarkable plasticity as atherosclerosis progresses. In atherosclerotic plaques, ECs and VSMCs display activated phenotypes () (3, 4). Some VSMCs form in the media after being recruited into the intima; others are derived from bone marrow or myeloid cells in the circulation (). (3). A small percentage of VSMCs proliferate () (3, 5). Extracellular matrix components are secreted by VSMCs, and the pluripotent transcription factor Klf4 can play a key role in phenotype switching (). (6, 7). Oct4 can regulate a process known as remigration to form a fibrous cap () (4, 8–10) in an attempt to protect the atherosclerotic plaque from lethal rupture. Senescence and apoptosis induce the development of more inflammatory cytokines, resulting in the formation of a necrotic heart, which sets off a vicious cycle with lethal clinical implications in the late stages of the disease () (3, 4, 11).

The cellular components of the normal blood vessel wall, vascular smooth muscle cells (VSMCs), provide structural stability and control the diameter by contracting and relaxing dynamically in response to vasoactive stimuli. Contractile cells are distinct VSMCs that are characterized by unique contractile proteins, ion channels, and cell surface receptors that control the contractile mechanism. VSMCs are responsible for the synthesis of extracellular matrix proteins, become migratory, and proliferate in response to injury or during development, in addition to these normal functions. Synthetic cells are the name given to this phenotype. Scientists have relied on cultured cells that can be controlled in vitro to better understand the mechanisms governing these and other processes. In this chapter, we’ll go over the explant method for VSMC isolation in detail and compare it to the enzymatic digestion method. We’ll also go through several strategies for analyzing the cells that result.

Vascular development and remodeling

Vascular smooth muscle contracts and relaxes to adjust the volume of blood vessels as well as local blood pressure, a process that enables blood to be redistributed across the body to where it is required (i.e. areas with temporarily enhanced oxygen consumption). As a result, the primary function of vascular smooth muscle tone is to regulate the size of blood vessels in the body. High blood pressure is induced by excessive vasoconstriction, while low blood pressure is caused by excessive vasodilation, as in shock.
Arteries have a lot more smooth muscle in their walls than nerves, which is why they have thicker walls. This is due to the fact that they must transport pumped blood from the heart to all of the organs and tissues that need oxygenated blood. Each has a similar endothelial lining.
