Percent male phenotype at varying times after 1 Gy WBI.
A total of 40 × 106 male BALB/c marrow cells were transfused into female BALB/c mice immediately (time 0) or 6, 12, or 24 weeks after host exposure to 1 Gy WBI. Percentage male DNA in female marrow is presented as determined by FISH (see “Materials and methods”). There were 5 mice per experiment, except for 1 experiment at 12 weeks, which had 2 mice. There were 5, 4, 3, and 1 experiments at time 0, 6, 12, and 24 weeks, respectively. Nonirradiated mice showed an average of 7.7% engraftment with 40 × 106 cells (58 mice). Data are expressed as a mean ± 1 SD.
