Cytometry to Evaluate iPSC Pluripotency During Cell Line Selection and Differentiation
Authors: Kirsty McBain, Daryl Cole, Nina Senutovitch, Nicola Bevan and Clare Szybut | Last updated: July 2022
When generating induced pluripotent stem cells (iPSCs) for use in downstream applications, it is commonplace to perform initial checks for key attributes such as viability and pluripotency. This allows for assessment of the quality of the produced iPSC culture, which may differ, due to numerous factors such as the reprogramming technology used.
It is therefore important that we have simple, robust, and standardized techniques for evaluating and comparing individual iPSC lines, to ensure we choose the best lines for lengthy and expensive studies.
Conventional techniques for evaluating iPSC pluripotency and differentiation, such as traditional flow cytometry, have their drawbacks.
The development of alternative simple and robust methods, for monitoring iPSC differentiation has promise to enhance the scalability and throughput of applications utilizing iPSCs, such as liver toxicity screening.
Here we describe a combined iQue® Advanced Flow Cytometry and an Incucyte® Live-Cell Analysis approach for stem cell evaluation during cell line selection and differentiation. Hence creating a streamlined workflow for iPSC characterization, which measures differentiation marker expression over time. This method has potential applications in research and drug discovery.
