Histologic analyses.

Representative skin (A-D) and liver (E-H) sections from different groups of mice (H&E stain, ×100). Arrowhead shows BCL1 leukemia/lymphoma cells growing in the liver; arrow shows infiltrating lymphocytes; asterisk shows fibrosis of portal tracts in the liver. Analyses included 4 groups of mice: a normal BALB/c mouse inoculated with BCL1 30 days ago (A,E); a BCL1-bearing mouse transplanted with T-cell–depleted bone marrow cells only (B,F; day +30); a BCL1-bearing mouse transplanted with T-cell–depleted bone marrow cells plus untreated primed cells (C,G; day +38); a BCL1-bearing mouse transplanted with T-cell–depleted bone marrow cells plus PDP-treated (20 μM) primed cells (D,H; day +126).
