Abstract

In the present invention, a cardiomyocyte cluster is disposed on a transparent substrate, and the quality of the cardiomyocytes is evaluated from the response of the cells to a forced pulsation stimulus applied to the cardiomyocytes. The cardiomyocyte cluster is disposed on the transparent substrate, and is exposed to the flow of a liquid containing an agent in a manner so that the agent acts on the cells, which configure a network. The extent of cardiac toxicity resulting from the agent is evaluated from measuring the fluctuations obtained from a comparison of adjacent cardiomyocytes of the network.
