title: Design of a novel rotating wall bioreactor for the in vitro simulation of the mechanical environment of the endothelial function.
abstract: Endothelial cells (ECs), besides being a permeability barrier between the blood and vessel wall, perform many important functions, e.g., cell migration, remodeling, proliferation, and the production, secretion and metabolism of biochemical substances, as well as the regulation of contractility of vascular smooth muscle cells (SMCs). Their function is modulated by chemical ligands as well as mechanical factors. The mechanical stresses acting on the vessel wall include the normal and circumferential stresses that result from the action of blood pressure, the shear stress that acts parallel to the luminal surface of the vessel due to blood flow and the magnitude and orientation of the gravitation field. The aim of this work was to design and construct a novel bioreactor for the stimulation of endothelial cells in vitro with a combination of mechanical factors that simulates their in vivo environment.
