  • Publication number: 20030175847
    Abstract: The present invention relates to a method of preparing primary heart muscle cells, characterized by washing a fine fragmented heart tissue with a phosphate-buffered physiological saline to thereby eliminate non-heart muscle cells and then hemolyzing the heart tissue digested with a protease to thereby eliminate erythrocytes. According to this method, highly pure primary heart muscle cells can be conveniently obtained in a large amount from the heart of an animal embryo or newborn. By using the heart muscle thus prepared, apoptosis of heart muscle cells can be efficiently and highly sensitively detected. Thus, it is possible to efficiently screen candidate compounds for heart muscle cell apoptosis inhibitors, gp 130-mediated receptor agonists, heart muscle cell-protective signal enhancers, preventives and remedies for heart diseases.
