Delayed platelet count recovery.
Delayed recovery of platelet counts in IL-7–treated (filled symbols) compared with placebo-treated (open symbols) animals. Animals were treated with IL-7 or placebo between 6 and 10 weeks after transplantation (indicated by the black horizontal bar). The differences in platelet counts were significant (mean 23 versus 99 × 109/L at week 8, P = .03; 17 versus 121 × 109/L at week 10, P = .002; and 23 versus 148 × 109/L at week 12, P = .004). “Norm” shows values determined in normal animals of similar age as the animals receiving transplants.
