Figure 7. Detection of transplanted mesenchymal stem cells in the kidneys of dogs with and without acute kidney injury (AKI). Cell transplantation with green fluorescent protein (GFP)-labelled canine umbilical blood-derived mesenchymal stem cells (cUCB-MSCs) was confirmed by confocal laser microscopy. Hoechst 33238 stained the nuclei in all kidneys. GFP-positive cells were detected in tubules in the AKI+MSC group (A–F, white arrows indicate GFP-positive cells, scale bar=50 μm). The kidneys of the AKI+PBS and l groups did not show the presence of GFP-positive cells (G–J, scale bar=50 μm).
