MUSCLE STEM CELL OR MYOBLAST, METHOD FOR SCREENING SUBSTANCES THAT PARTICIPATE IN METABOLIC CONVERSION USING SAME, AND PHARMACEUTICAL COMPOSITION COMPRISING SUBSTANCE OBTAINED FROM SAID SCREENING METHOD

摘要

The purpose of the present invention is to provide a method for screening substances that participate in metabolic conversion and a kit for screening substances that participate in metabolic conversion. Said problem can be solved with muscle stem cells or myoblasts comprising at least one myosin heavy chain fusion gene selected from a group consisting of: a myosin heavy chain I fusion gene in which a myosin heavy chain I gene is bonded to a fluorescent or luminescent protein gene; a myosin heavy chain IIa fusion gene in which a myosin heavy chain IIa gene is bonded to a fluorescent or luminescent protein gene; a myosin heavy chain IId/x fusion gene in which a myosin heavy chain IId/x gene is bonded to a fluorescent or luminescent protein gene; and a myosin heavy chain IIb fusion gene in which a myosin heavy chain IIb gene is bonded to a fluorescent or luminescent protein gene.
