Photomicrographs of 4',6-diamidino-2-phenylindole (DAPI) staining and green fluorescent protein (GFP)-positive cells in the injection sites of intervertebral disc tissue at 48 hours, 1 week, 2 weeks and 4 weeks post injection of mesenchymal stem cells infected with adenoviral vectors carrying the GFP transcript.
