A multicenter, retrospective medical record review of X-linked myotubular myopathy: The recensus study.

abstract：:The cross-sectional area of the fibers of hindlimb muscles of rats increased 10-40 times during the first 6 weeks after birth. Denervation at birth stopped the growth of the muscle fibers. The number of satellite cells decreased, and eventually all fibers vanished. Reinnervation, if any, was poor. Partial denervation ...
