Figure 5. Clinical examination by slit lamp microscopy and histopathology of corneal allografts. A: Representative images of the corneal allograft in each experimental group. B: Histopathological evaluation for corneal sections using H&E staining (40×). Graft rejection was observed in the corneal necropsy specimens of the BMT recipients for the SEB-BMT, CYP-BMT, and NS-BMT groups by Day 21 after BMT (Day 14 after corneal transplant). Lymphocyte infiltration and neovascularization were significantly decreased in the SEB-BMT group compared to the CYP-BMT and NS-BMT groups.
