Detection of green fluorescence protein (GFP) mesenchymal stromal cells (MSCs) labelled with Cell Sense Red in the cranial lobe of rat lung at T48. a Image of right cranial lobe of rat lung and indicative direction of MSC injection. b Confocal fluorescence image of right cranial lobe injected with Cell Sense–labelled GFP-MSCs (20× objective, scale bar 100 μm) and zoom on a restricted area (40× objective, scale bar 50 μm). The lung was counterstained with 4′,6-diamidino-2-phenylindole (nuclei). c Representative detailed zoom on GFP (green) and Cell Sense–labelled (red) MSCs through structured illumination microscopy (single-plan image) and three-dimensional volume of 4 μm z-stack of single Cell Sense-MSC (scale bar 5 μm)
