Immunolabeling with antibodies against desmin (green in A, E, and I), laminin (red in B, F, and J) and keratin 19 (gray in D, H, and L) in EOMs. Merged images of desmin and laminin are shown in C, G, and K. Keratin 19 was absent from MTJs and the remaining parts of the myofibers containing desmin along their length (thick arrows in A–D) or only in the vicinity of the MTJs (thin arrows in E–H), or in myofibers completely lacking desmin (arrowheads in I–L). Bars = 20 µm.
