B, Gross image of an acutely rejected recipient’s graft 1 week after VCA. C, Gross image of a chronic KO rejected recipient’s graft 2 weeks after VCA. D, Gross image of a chronic BM12 rejected recipient’s graft 6 weeks after VCA. E, H&E-stained image of a skin section from syngeneic recipient 4 weeks after VCA. Scale bar; 100 µm. F, H&E-stained image of a skin section from acute rejection recipient 1 week after VCA. Scale bar; 100 µm. G, H&E-stained image of a skin section from chronic KO recipient 2 weeks after VCA.
