Research is exploring the role of vascular smooth muscle cells in coronary disease risk, with studies using single-cell and spatial transcriptomics to investigate molecular mechanisms. These studies are examining various aspects of vascular smooth muscle cell behavior, including phenotypic switching, metabolic reprogramming, and interactions with other cell types. The findings may shed light on the underlying mechanisms of coronary disease and related conditions, such as atherosclerosis and thoracic aortic aneurysm.
