Extended Data Table 1 Skeletal muscle mitochondrial cross-sectional diameters

From: Mitochondrial reticulum for cellular energy distribution in muscle

  1. FIB-SEM, focused ion beam scanning electron microscopy; STED, stimulated emission depletion microscopy; PVM, paravascular mitochondria; IBM, I-band mitochondria; FPM, fibre parallel mitochondria; CFCM, cross fibre connection mitochondria. Statistical test was analysis of variance (P < 0.05). There were no significant differences between FIB-SEM and STED. Diameters were measured at the maximum cross-section of the short axis of the mitochondria which were roughly ellipsoidal or cylindrical in shape. STED diameters were determined by the full-width half-maximum (FWHM) of the linear fluorescence intensity profile, and FIB-SEM diameters were determined as the distance of a line drawn across a mitochondrion.
  2. *Denotes significantly different from PVM.
  3. Denotes significantly different from IBM.
  4. #Denotes significantly different from FPM.
