METHOD FOR CONSTRUCTING MASS OF MYOCARDIAL CELLS AND USE OF THE MYOCARDIAL CELL MASS

摘要

It is an object of the present invention to improve the engraftment rate of purified myocardial cells so as not to include cells other than myocardial cells but to include components derived from other species. In order to solve the above problems, the inventors of the present invention examined whether purified myocardial cells can build up a cell mass. As a result, the purified pluripotent stem cell-derived myocardial cells obtained by dispersing aggregated cell masses containing differentiated and induced myocardial cells from pluripotent stem cells into single cells were cultured in a serum-free medium, The present inventors have made it clear that the above problems can be solved by providing a method for producing cell masses of cardiomyocytes derived from pluripotent stem cells.
