In a recent study led by Associate Professor Yoshinori Yoshida (Department of Cell Growth and Differentiation) and published in Communications Biology, a team of researchers identified CD151 as a marker for distinguishing subtype-specific cardiomyocytes during differentiation from human iPS cells (hiPSCs). In addition, they found a novel method to generate functional atrial cardiomyocytes with improved efficiency compared with the conventional differentiation method.
