(B) Immunopositive tissue macrophages and dendritic cells (brown) in spleen at day 7. (C) TUNEL-positive (brown) lymphocytes and scattered tingible body macrophages in an axillary lymph node at day 7. (D) TUNEL-positive (brown) lymphocytes and scattered tingible body macrophages in an axillary lymph node at day 17. (E) Immunopositive tissue macrophages, endothelial cells, and dendritic cells (brown) in spleen at day 13. Inset is enlargement of indicated area (arrow) showing dendritic cell.
