Characterization of DN tumor precursor cells in ThPOKconst mice. (A) FACS analysis of gated TCR DN (CD4CD8) thymocytes from 5-wk-old ThPOKconst mice and WT littermates. Note the relative increase in the DN4 (CD44CD25) fraction in all ThPOKconst mice, and the appearance of CD44INT cells, which also express variable levels of CD25, in a subset of ThPOKconst animals (Bottom row; CD44INT population is outlined in red). (B) A total of 25–100 × 103 sorted DN thymocytes from indicated mice were transferred into sublethally irradiated Rag2−/− recipient mice, and PBLs were analyzed by FACS for CD4 and CD8 expression at indicated times.
