Cultured muscle cells with high metabolic activity and method for production of the cultured muscle cells

摘要

The object of the present invention is to provide a method of preparing excellent cultured muscle cells having high metabolic capacity and insulin responsiveness, and further provide a method for the measurement of sensitive metabolic capacity using the cells. The present invention is a method of preparing myotube cells, comprising a step (1) of culturing myoblast cells, a step (2) of differentiation-inducing the myotube cells into the myoblast cells in a culture medium with a high content of amino acids, and a step (3) of applying an electric pulse to the differentiation-induced myotube cells.
