Figure 5. — Plantaris MTJ from a rat in the EX (a), GH (b), and GH+EX (c-f) group. a) Tissue condition appears restored and more similar to control compared to the UNL group. The finger-like processes are clearly observable. b) The muscle-tendon interface is similar to UNL group, with rare, irregular and short interdigitations. c) The muscle-tendon interface appears more folded than in the GH and EX groups, presenting several long and branched interdigitations. d) The muscle structure seems to be comparable to that in the CTRL group, with well aligned sarcomeres and regularly distributed myofilaments. e) At high magnification, a normal organization of cytoplasm is evident, with the typical disposition of mitochondria and triads in the thin intermyofibrillar space. f) Myofilaments appear in close contact with tendon tissue. M: muscle; T: tendon; m: mitochondria; t: triads. Scale bars: a,b,c, 2 μm; d, 0.5 μm; e,f, 0.25 μm.
