CD8 T- and B-cell counts in blood and LNs.

Counts of CD8 T cells (A,C) and B cells (B,D) in blood and percent CD8 T cells (E) and B cells (F) in axillary LNs. Animals were treated with IL-7 (filled symbols) or placebo (open symbols) between 6 and 10 weeks after transplantation (indicated by the black horizontal bar). “Norm” shows values determined in normal animals of similar age as the animals receiving transplants. In one placebo-treated animal, LN sampling at 5 to 6 months after transplantation was not done. For the LNs, percents of total LN cells are given.
