Figure S1. Positive controls were stained in parallel with the cases and each showed the expected pattern of immunoreactivity. CD31 (brain, A), CD34 (brain, B), CD45 (tonsil, C), CD68 (brain, D), CD133 (pancreas, E), DCX (brain, F), EMA (brain, G), GFAP (brain, H), HLA-DR (tonsil, I), Ki67 (small intestine, J), MAP2 (brain, K), nestin (brain, L), Oct3/4 (germinoma, M), SOX2 (focal cortical dysplasia, N), TUJ1 (small intestine, O), vimentin (brain, P). All images × 20 objective.


Figure S2. The rod cells (arrows) were negative for the immunostains CD31 (A), CD133 (B), EMA (C), GFAP (D), MAP2 (F), Oct3/4 (G), SOX2 (H) and vimentin (I). An occasional rod cell was positive for Ki67 (white arrow, E), an epitope that is particularly prone to post mortem degradation. All images × 20 objective.
