Project description
Cardiovascular disease stands as a leading cause of death, where arterial stiffening emerges as a risk factor during atherogenesis and vascular injury. In this context, vascular smooth muscle cells (VSMCs) undergo a transition from contractile to synthetic phenotypes, migrating, proliferating, and contributing to neointimal and atherosclerotic plaque formation, alongside local inflammation. Recent studies using mouse models of vascular injury and atherosclerosis suggest that only a subset of VSMCs drives neointimal and atherosclerotic plaque formation, indicating heterogeneity among VSMCs in various pathophysiological states. This proposal aims to assess the impact of arterial stiffness on VSMC heterogeneity, encompassing changes in phenotype, morphology, cell proliferation, and cell motility.
The outcomes will reveal: (1) the misinterpretation of the predominant paradigm on VSMC phenotypic switching in arteries based on average data, and (2) how individual VSMCs respond uniquely to matrix stiffening, essential for a fundamental understanding of CVD progression.
Project outcome
Students will develop critical thinking skills and gain exposure to the scientific method by learning experimental techniques such as immunoblotting, immunostaining, RT-qPCR, microscopy, and image analysis. They will interpret their own data on VSMC phenotype, morphology, cell proliferation, and motility in response to matrix stiffening, and explore the unique responses of individual VSMCs to understand implications for cardiovascular disease progression. Additionally, students will engage in effective oral and written communication while collaborating with their research mentor and lab members. They will also have opportunities to present their work at local and international conferences and contribute to research articles.
