Immunofluorescence analysis of infiltrating cells. At termination of the therapy experiment a comparative immunofluorescence analysis of infiltrating cells from mice treated with saline or F8-IL10 was performed. (a) Representative immunofluorescence images of paw sections. Scale bars = 100 μm. (b) Sections were evaluated for area percentage positive staining and a significant decrease of infiltrating leukocytes was observed. * P < 0.05 versus saline.
