Figure 6. Immunohistochemistry of immune infiltrates from xenografts removed from F5/hdCK3mut animals.
(A) Schematic of xenograft location on F5/hdCK3mut animals. (B) H&E histology of M202 (HLA-A*0201+) and M207 tumors (HLA-A*0201–). The white line distinguishes viable tumor from tumor necrosis. (C) Anti-CD3 and (D) anti-CD8 staining of representative sections of M202 or M207 xenografts. Black arrows point to T cells. Scale bar: 50 μM.
