High densities of mitochondria between centrally localized nuclei or regenerating mdx muscle cells. A representative transmission electron microscopy micrograph of a regenerating dystrophin-deficient tibialis anterior muscle cell with centrally localized nuclei (A). Higher magnification image of panel A (B). Large numbers of mitochondria localize to the intermyonuclear space between centrally localized nuclei of regenerating mdx muscle cells. N indicates a centrally localized nucleus. Scale bars in (A) and (B) represent 2 and 1 μm, respectively.
