Single fibre zone dimensions. Dimensions of single muscle fibres obtained from control and regenerating human vastus lateralis muscle in 4 individuals (1–4), 7 days after injury. Individual data points with the mean are displayed. Within the damaged fibre (a), note the repeating pattern of regenerating (thinner) and necrotic (wider) zones (inverted wide-field immunofluorescent image of laminin staining, 500 μm scale bar). Within the damaged fibres, the diameter of the regenerating zones was significantly less than the diameter of the necrotic zones (b) and the control and undamaged fibres in the injured leg (c), p < 0.05. Displayed in d are the lengths of the regenerating and necrotic zones in the damaged fibres. The full length of the fibre fragments obtained during the isolation procedure is presented in e
