Endothelial research focuses on the study of endothelial cells, which are a type of cells that line the interior surface of blood vessels and play a crucial role in maintaining vascular function. These cells regulate important processes such as blood flow, blood clotting, and the movement of molecules and cells into and out of the bloodstream. Research in this area includes understanding the molecular mechanisms that govern endothelial cell function, how these cells contribute to health and disease states, and the development of new therapies to target endothelial dysfunction in conditions such as cardiovascular disease, cancer, and diabetes.
