Quantum dots (QDs) are semiconductor nanocrystals with unique photo-physical properties. QDs are brightly fluorescent and photostable, and therefore represent a novel class of fluorescence probes for bio-imaging and cell monitoring. There are different techniques for labeling cells with QDs. Moreover, there is evidence that optical properties of the QD can be changed as a result of interaction with live cells. This manuscript describes a simple method for labeling of rat endothelial progenitor cells using ODs and for characterization of their optical properties. © 2012 Springer Science+Business Media, LLC.
