Figure 2: (A): The immunofluorscent staining performed on tissue biopsy samples revealed the GFP positive cells existed in the alloskin and recipient skin and recipient liver and spleen parenchymal tissues 2 weeks post-ASC injection. (B): GFP positive cells in different immunofluorscent staining tissues were counted by using semi-quantitative analysis. Abbreviations: GFP: Green Fluorescent Protein; HE: Hematoxylin-Eosin; and DAPI: 4’,6-diamidino-2-phenylindole.
