Despite advances in the visualization of pre-labeled SCs with perfluorocarbon-ether-nanoparticles (PFCE-NPs) or other MRI contrast agents using 19F MRI, there have been no prior reports on murine cardiac 19F imaging of exogenously administered cardiac SCs following direct, intra-cardiac injections. To-this-date, human or murine in vivo cardiac studies have been limited, while prior reported imaging attempts in rats have been prohibitively lengthy, costly (use of multiple millions of cells/animal), and practically complex to reproduce in mice. We report herein significant enhancements of PFCE-NP label following labeling with the highly efficient agent FuGENE, thereby allowing in vivo murine cardiac 19F MRI visualization with minimal cellular toxicity.
