Distribution of population characteristics for the donor pool of 41 iPSC-derived cardiomyocytes. (A) Distribution of population characteristics in the USA in 2018 and in this study, in terms of ancestry (outer ring) and sex (inner circle). (B) Scatter plot of the 1st and 2nd principal components for genotypes across donors, with colors and shapes representing the different ancestral backgrounds and sexes, respectively, presented in (A). Large symbols represent principal components for our population of 41 donors, and small symbols represent principal components for ~1000 human lymphoblastoid cell lines from the 1000 Genomes project.
