Load dependency measurement of IPS cell-derived cardiomyocytes' contraction

摘要

In this paper, we propose a method to evaluate relationships between twitch forces and static stretch stimuli of iPS cell-derived cardiomyocytes (iPSC-CMs) (force-length relation). The method realized the twitch force measurement of iPSC-CMs statically stretched under the culturing condition. As a result, twitch forces of a few tens of μN were measured, and the variation of twitch forces was observed as the static stretch was increased.
