Fig. 3. (A) The expression of TN-C can be seen both at the MTJ and the microtendon
(arrows). (B) Strong expression of TN-C can also be detected in the myofascial
junction, whereas the endomysial and perimysial connective tissues are
negative for TN-C immunoreactivity. (C) Only TN-C immunoreactivity that can be
detected in the skeletal muscle is visible in the intramuscular
myofiber-myofiber junctions at the tips of muscle cells (arrows). (D) In the
tendon, immunohistochemical expression of TN-C is visible in the
tenocytecollagen-fiber interface (arrows) as well as on the surface of
the collagen fiber bundles of the Achilles tendon. Magnification: A,C,D
