Project: Endothelial Mechano-Biology Research
Professor: Eno Ebong
Project Description: We seek to define endothelial cell and glycocalyx mechanisms of blood vessel regulation by solid-fluid mechanics. The project tests the hypothesis that fluid (blood) and solid (blood vessel wall) forces cooperate to regulate endothelial cell behavior via the glycocalyx, a sugar complex that is anchored to and coats endothelial cells and can convert fluid and solid force stimuli into cellular responses. Endothelial cells lie at the vascular fluid-tissue interface and play an essential role in maintaining blood vessel health. An incomplete knowledge of endothelial cell mechanobiology mechanisms results in limited vascular disease prevention and treatment efficacy. This project will address this critical knowledge gap.
Learning Objectives: (1) Characterize glycocalyx architecture; (2) Link glycocalyx structure to cell molecular mechanisms; (3) Clarify how molecular stimuli evoke an endothelial cell response that impacts production of nitric oxide, a vasodilator.
