Resumen:

Cell-cell fusion is a frequent event in nature leading to modifi cation of cell fate. In this chapter, we describe a flow cytometric procedure for the quantitative assessment of in vitro cell-cell fusion events that allows the discrimination of fused from aggregated cells. The assay is based on the differential labeling of fusion partners with lipophilic fluorescent probes DiI (red) and DiO (green). Double fluorescent fused cells can be detected after coculturing by means of a flow cytometer equipped with a 488 nm laser. Fusion events can be distinguished from cell aggregates by the enhancement of the DiI red fluorescence intensity due to resonance energy transfer between the two probes occurring in the fused but not in the aggregated cell population. © Springer Science+Business Media New York 2015.
