Thymocyte numbers correlate with T-cell exit into the periphery. Adult C57BL/6 mice were first treated either with KGF (⊡) or HBSS (▪) as in Figure 1 and then intrathymically injected with FITC (10 μL) 7 or 44 days later. After 24 hours of in vivo labeling, the export of thymus-derived cells into the periphery was assessed by enumeration of FITC-positive cells (× 10−6) on day 8 (A) and day 45 (B). Mean ± SD; *P < .05 versus HBSS controls, with 6 mice per group and time point.
