This thesis introduces a microfluidic device developed to investigate the influence of hypoxia and shear stress on endothelial cell behavior. Endothelial cells are critical in inflammation, cardiovascular diseases, and cancer growth. The microfluidic device enables precise control of oxygen distribution and shear stress conditions within a cell culturing chamber, facilitating multiplex testing. By subjecting endothelial cells to varying hypoxia and shear stress levels, intracellular oxidative stress was evaluated through reactive oxygen species (ROS) measurements and cell morphology analysis. The findings indicate that hypoxia and shear stress can modulate ROS expression, offering valuable insights into vascular diseases and exercise-related research. The device provides a more physiologically relevant cell culturing environment than conventional methods, and its potential applications extend to anti-cancer medication testing, oncological studies, and cardiovascular disease investigations. In summary, the developed microfluidic device is a valuable tool for understanding the underlying mechanisms governing endothelial cell behavior in response to hypoxia and shear stress. The precise control over oxygen distribution and shear stress conditions facilitates comprehensive investigations into the effects of these factors, thereby contributing to advancements in the field of vascular biology and related disciplines.
