Depletion of various precursors results in thymocytopoiesis progressing with different kinetics. CD4 versus CD8 profiles of experiments performed as described in Figure 2. (A) Analysis 2 weeks after transfer. One representative of 8 individual mice is shown. (Top panels) Competitor population. (Bottom panels) Test population. Numbers in quadrants indicate the percentage of cells. (B) Analysis 4 weeks after transfer. One representative of 8 individual mice is shown. (Top panels) Competitor population. (Bottom panels) Test population. Numbers in quadrants indicate the percentage of cells. (C) Proportions of DP (left panel) and SP (right panel) thymocytes within test (black bars) and competitor (gray bars) populations 4 weeks after transfer. Data are shown as mean ± SEM; *P < .05; ***P < .001; n = 8.
