Pluripotent stem cells have therapeutic potential in many areas of medicine because of their ability to differentiate into specific cells and tissues needing repair. This process of differentiation is not 100% efficient, which presents challenges when scaling for use in regenerative cell therapy. To improve quality control for stem cell derived tissues in a clinical setting, there is a need to non-invasively monitor and predict differentiation.
In this article, the authors highlight an optical approach using multiphoton excitation from a Bruker Ultima microscope to measure metabolic changes throughout the differentiation of pluripotent stem cells to cardiomyocytes. This technique of Optical Metabolic Imaging takes advantage of the intrinsic fluorescence of metabolites such as NAD(P)H and FAD, including the fluorescence lifetime measurement capabilities of the microscope, to distinguish between metabolic states. In their model, they show that this autofluorescence measurement of metabolism can predict cardiomyocyte differentiation outcome early and reliably.
