Fig. 6. Integrin complexes are maintained at the MTJ. (A,B)
MTJs in diaphragm muscle from wild-type and Tln1 mutant mice were
analyzed by transmission electron microscopy to reveal the lamina densa. A
continuous basement membrane (arrowheads) was present at the MTJ in mutants.
(C-N) Localization of collagen IV, laminin, integrin 
7β,
vinculin, Ilk and talin 2 at MTJs (arrowheads) was analyzed by
immunofluorescence microscopy. All analyzed proteins were present at MTJs in
wild-type and mutant animals. t, tendon, m, muscle. Scale bars: 500 nm in A,B;
100 µm in C-F; 200 µm in G-N.
