Recovery of cells from various organs of either infected or noninfected BALB/c nude mice that had received 107 CFSE-labeled P. berghei- or Ova-specific T cells 7 days earlier. Three mice in each group were studied; cells from individual spleens and pooled cells from other tissues were assessed. Data are the number of CFSE+ cells per spleen (A), per two inguinal lymph nodes (B), per ml of blood (C), per the whole lung (D), per the whole liver (E), and per two femurs (F).
