BIAXIAL STRAIN SYSTEM FOR CULTURED CELLS

摘要

Biological cells plated on an elastic membrane (14) are placed under biaxial strain for purposes of observation by a device that includes a support (12) with an opening over which the membrane (14) is secured, a movable cylinder (11) coaxial with the opening and fitting closely but movably within the opening, and an actuating member (13) that stabilizes and controls the position of the cylinder (11) relative to the opening. The actuating member (13) is coupled to the support (12) by a threaded connection while engaging the movable cyclinder (11). The degree of membrane stretch is accurately controlled by the rotation of the actuating member (13).
