Data are expressed as mean ± SD. The Mann-Whitney U test has been used to compare the lymphocyte counts in each group. After gene therapy, the comparison between the thymocyte counts in the 3 Gy- and 8 Gy-irradiated recipient is statistically significant (P < .05). No significant difference was observed in lymph nodes, spleen, and bone marrow cell counts.

RAG-1–/– indicates RAG-1-deficient mice; RAG1-TM, RAG1-transduced mice; and WT-CTRL, control mice.
