Abstract

Human pluripotent stem cell (hPSC) derivatives are valuable for a variety of research applications and have the potential to revolutionize approaches to personalized medicine. However, differentiation efficiency varies among cell lines and protocols. Therefore, methods to reliably determine cell type identity in cultures of hPSC derivatives in a manner that is consistent among laboratories are needed. While flow cytometry is apt for routine assessment of population heterogeneity, standardized protocols are not available for most cell types. This article describes a workflow for establishing a fit-for-purpose protocol for flow cytometric analysis of hPSC derivatives. Based on the application of this workflow, a standard operating procedure (SOP) was developed for the analysis of cardiac troponin in hPSC-derived cardiomyocytes (hPSC-CM). Throughout the article, important concepts related to antibody validation and gating strategies are presented to enable users to properly validate any antibody of interest and develop a rigorous SOP for their experimental needs.
