Fig. 5. Numbers of donor myoblasts in irradiated and contralateral (protected) TA muscles in NK-depleted mdx host mice where MTT was performed at 1 hour after local irradiation and muscles sampled at 1 hour, 24 hours, 1 week, 3 weeks, 12 weeks and 24 weeks after MTT. Schematics of the irradiation treatment of host mice (see Fig. 1) are indicated in the top right hand corner. Bars indicate s.d. *P<0.05, **P<0.005 (untreated to treated samples) using ANOVA; d and dd indicate significances of P<0.05 or P<0.005, respectively, between treatment groups at each time point using ANOVA (n=6 unless otherwise stated).
