Internalized Au NPs do not affect surface marker expression of MSCs. Representative histograms of 3 independent experiments of the distribution of the marker fluorescence N(Imarker) of MSC-defining surface markers of untreated MSCs (black solid line) and MSCs exposed to Au NPs at cNP = 10 nM (red dashed line) for 48 h are shown. The solid grey front curve represents the isotype control
