Figure 3: (A) The immunofluorscent staining performed on tissue biopsy samples revealed no apparent expressions of ASC-GFP+ cells were found in recipient tissues at 16 weeks post-transplantation except spleen parenchymal tissue. These indicated donor ASCs could be long-term existence in the recipient spleen. (B) Semi-quantitative analyses of GFP positive cells in different immunofluorscent staining tissues were counted. The indicated signals were statistically significant (P<0.05). Abbreviations: GFP: Green Fluorescent Protein; HE: Hematoxylin-Eosin; and DAPI: 4’,6-Diamidino-2-Phenylindole.
