The aim of the present work was to standardize the working methodology for assessing the bioenergetic profile of H9c2 cardiomyoblasts cells, with reference to the optimization of cell seeding number and the establishment of favorable concentrations for the classic modulators of mitochondrial respiratory function, in particular the one of a classical uncoupler, FCCP.
Material and methods: The extracellular flux analyzer (XF, Seahorse Bioscience) is a novel high-throughput instrument able to monitor the metabolism of living cells by simultaneously measuring mitochondrial respiration and glycolysis. The in vitro platform will be further used to better understand the pathophysiology and the unrecognized side effects of drugs currently used in the therapy of major cardiovascular diseases.
Conclusions: In the long run, characterization of novel pharmacological agents' effects on other cell lines, including tumoral ones, will be also considered.
