Abstract
Human-induced pluripotent stem cells are known for their high proliferation capacity as well as their ability to differentiate to different lineages (Ban et al., Theranostics 7(7):2067-2077, 2017; Chen et al., Stem Cell Res 15(2):365-375, 2015; Serra et al., Trends Biotechnol 30(6):350-359, 2012). For stem-cell-derived cardiomyocytes to evolve into a scalable therapeutic source, a large quantity of highly pure cardiomyocytes is needed. Thus, lies the challenge of defining an efficient cardiomyocyte differentiation process. This chapter describes a method to evaluate multiple human-induced pluripotent stem cell lines for their cardiac differentiation potentials before evaluating their integrated proliferation and differentiation abilities in microcarrier cultures in a spinner culture format.
