Project description:Currently, it is well established that human endothelial cells (ECs) are characterised by a significant heterogeneity between distinct blood vessels, e.g., arteries, veins, capillaries, and lymphatic vessels. Further, even ECs belonging to the same lineage but grown under different flow patterns (e.g., laminar and oscillatory or turbulent flow) ostensibly have distinct molecular profiles defining their physiological behaviour. Human coronary artery endothelial cells (HCAEC) and human internal thoracic artery endothelial cells (HITAEC) represent two cell lines inhabiting atheroprone and atheroresistant blood vessels (coronary artery and internal thoracic artery, respectively). Resistance of the internal mammary artery to atherosclerosis has been largely attributed to the protective phenotype of HITAEC which reportedly produce higher amounts of vasodilators including nitric oxide (NO) through the respective signaling pathways. However, this hypothesis has not been adequately addressed hitherto as proteomic profiling of HCAEC and HITAEC in a head-to-head comparison setting has not been performed.
Project description:Analysis of the effects of cell shape on human coronary artery endothelial cell transcription. The hypothesis is that defined alterations in endothelial cell shape uniquely affect the endothelial transcriptome. Human coronary artery endothelial cells were plated onto spatially defined micropatterns (Cytoo) forcing them to conform to Disc, Crossbow, H, Y, or L shapes. As a control, human coronary artery endothelial cells were plated on non-restrictive areas of the Cytoo growth plate.
