Efficacy of chimeraplast-mediated dystrophin expression

Chimeraplast	No. of dystrophin-positive fibers
MDX1	24, 16, 32, 18, 9, 27
Control	0, 0, 0, 0, 0, 0

A series of 12 tibialis anterior muscles of mdx mice were injected with chimeraplasts, 6 with MDX1, and 6 with control. The groups of mice were matched for age and all injection procedures. All mice were injected at 14 days of age and sacrificed 2 wk later. The data presented are from the cross section with the maximum number of dystrophin-positive fibers from each muscle.
