Fig. 1From: In vitro labelling and detection of mesenchymal stromal cells: a comparison between magnetic resonance imaging of iron-labelled cells and magnetic resonance spectroscopy of fluorine-labelled cellsCell Sense-labelled MSCs and MIRB-labelled MSCs. MSCs were labelled with Cell Sense (10 mg/mL, green fluorescence; a and c) or with MIRB (50 μg/mL, red fluorescence; b and d). Nuclei were counterstained with DAPI (blue). Images were acquired by confocal microscopy (a and b) and by structured illumination microscopy (c and d). Scale bars: a and b, 100 μm; c and d, 5 μmBack to article page
