Levels of IL-7 transcripts in the thymus after BMT.

(A) Real-time RT-PCR plots of amplification of IL-7 from the thymuses of representative mice obtained 5 days after 650 cGy, 1000 cGy, and 1400 cGy and from a normal unirradiated mouse. (B) Copies of IL-7 transcripts per thymus in mice 5 and 28 days after BMT, expressed as copy numbers per thymus after 650, 1000, or 1400 cGy (n = 5 for all groups; P < .05 for all irradiated groups on day 5 vs normal; P > .05 on day 28). ▪ indicates day 0; ▤, day 5; ▥, day 28.
