Figure 2. Analysis of graft-infiltrating leukocytes. At the time points of corneal allograft rejection CD45⁺ leukocytes were stained and calculated within the graft. A: Histological staining of graft infiltrating CD45⁺ leukocytes is shown exemplarily. B: Calculation from 4 representative grafts revealed no statistically significant differences in the total amount of infiltrating cells in rejected grafts of 3.2.3- and control treated recipients, respectively (NS=not significant).
