Resumen
Method of measuring ex vivo vascular tone and flow chamber. The present invention relates to a method of measuring ex vivo vascular tone comprising: perfusing a constant flow of a cell suspension in an open circuit including a vessel whose tone is to be studied, closing the circuit, perfusing a krebs nutrient solution in the closed circuit and apply a constant transmural pressure, add a vasoactive substance and record the variations in diameter of the vessel by means of an image capture system located perpendicular to the vessel and coupled to a microscope. The invention also relates to a flow chamber in which to perform the method of measuring vascular tone that includes two glass capillaries, a bath, an infusion pump, a hydrostatic pressure system, a manometer, a thermoregulation system of the temperature of the bath and of the solutions and/or suspensions used, a system for capturing images and a microscope.
