Abstract: An injection instrument set includes a tubular injection instrument in which an injection liquid is contained, and a guide member disposed on a surface of an injection target of the injection liquid. The injection instrument includes an injection needle which is inserted into the injection target to inject the injection liquid into the injection target. The guide member includes a guide passage which is disposed at a predetermined angle with respect to a surface of the guide member which comes into contact with the injection target and which allows the injection needle to be inserted and guides the injection needle onto the surface of the injection target, and an anti-slip portion disposed at a portion at which the guide member comes into contact with the surface of the injection target.

Abstract: The object of the present invention is to improve the post-transplantation engraftment rate of cardiomyocytes that have been purified to such an extent that they are free from non-cardiomyocytes and any components derived from other species. To solve this problem, the present inventors studied the possibility of constructing cell masses from the purified cardiomyocytes. As a result, they revealed that the stated problem could be solved by providing a method of preparing cell masses of cardiomyocytes derived from pluripotent stem cells, characterized in that cell masses of aggregated cells containing cardiomyocytes that had been differentiated and induced from pluripotent stem cells were dispersed to single cells to thereby obtain purified cardiomyocytes, which were then cultured in a culture medium under serum-free conditions so that they were reaggregated.
