CLPs indicate common lymphoid precursors. See Table 1 footnote for other abbreviations.
Purified BM CLPs or the thymic CD4low precursors (1 to 2 × 104) were injected intravenously into lethally irradiated Ly 5.1 recipients. At various times after precursor cell transfer, donor-derived DC populations were analyzed, and the number of total donor-derived DCs and the number of each donor-derived DC population were calculated as described in Table 1 and expressed per 104 cells transferred. The data presented are means of 2 to 3 such experiments at each time point. Each experimental group included 3 mice.
