Regenerative processes that counteract perifascicular muscle atrophy and capillary loss in juvenile dermatomyositis (JDM) are not well characterized. We aimed to analyze the pattern of myo-regeneration in relation to vascular damage and repair in muscle specimens from JDM patients. Myogenic regulatory factors that are sequentially expressed during myogenesis were studied by immunohistochemistry. Capillary density, numbers of CD34+ endothelial progenitor cells within the endomysium and molecules implicated in angiogenesis were evaluated by double-immunofluorescence techniques.
