Used the silicon belt the expansion and contraction stimulus load device null for the cultured cell

摘要

PROBLEM TO BE SOLVED: To obtain the subject device capable of setting an expanding and contracting stimulation or extending stimulation imparted to culturing cells in high accuracy by using a belt-like silicone membrane as a carrier. ;SOLUTION: The subject device is constituted by using a silicone membrane formed into a belt-like shape as a carrier 1 and expanded and contracted by a high torque stepping motor and a lead screw 4. Two rods 2 are inserted in the interior of the silicone belt having cells, etc., added thereto, and are hung on right and left arms 3 respectively. An extending rate is set in a high accuracy within a range of 0% to at least 110% at 0.1% interval, and a change of a expanding and contracting acceleration, extending time, a moment stop, a frequency of the expansion and contraction, etc., is readily performed without changing a hard wear.;COPYRIGHT: (C)1998,JPO
