This method eliminates any major invasion during cell injections caused by the cell suspension solution.
In this work, the purpose is to improve the efficacy of regenerative medicines, especially heart regenerative medicine using induced pluripotent stem cells. Heart regenerative medicine is our most contributed research field. My significant findings include a metabolic selection of cardiomyocytes, i.e.
a simple and mass purification mass way for cardiomyocytes with cultural condition of withdrawn glucose and added lactate. Another finding includes the efficient engraftment method for cardiomyocytes by publication of cardiomyocyte poles. This transplantation method with cardiomyocyte poles confirmed the enhanced engraftments of cardiomyocyte poles.
However, the lack of direct interaction between the host and graft cardiomyocytes was found. This technique offers fewer invasions to the tissues receiving the cell injections. As a result of this, direct interaction between the host and graft cardiomyocytes was facilitated.
This technology can diminish injuries, inflammatory responses, and eventually fibrosis, i.e. scar formation. Hopefully, this technology will be applied to the next generation of regenerative medicines, including heart regenerative medicine using pluripotent stem cells.
We have already found several ways to bring significant merit to heart regenerative medicine. These studies will be continued in the future.
