Figure 1. Effect of 18 Gy Irradiation on Cross-sectional Areas and Central Nucleation in Limb Muscles from Wild Type and Het Mice.

Figure 1

A. Effect of 18 Gy irradiation on cross-sectional areas in leg muscle from wild type (wt) and mdx:utrophin+/− mice (het). *indicates significant difference from non-irradiated WT control. # indicates significant difference from non-irradiated het control. B. Effect of 18 Gy irradiation on central nucleation in leg muscle from WT and het mice. *indicates significant difference from non-irradiated WT control. # indicates significant difference from 18 Gy 7 day and 14 day het leg muscle. C. Photomicrograph of het leg muscle 60 days after gamma irradiation at 18 Gy. Arrow indicates a large group of very small myofibers. D. Photomicrograph of non-irradiated age-matched het leg muscle. Arrow indicates a myofiber with multiple centrally located myonuclei. Bar is 20 µm.
