Figure 5 - Anchoring junctions between the detached cuticle and the apical part of tendon cells in the prehatching embryo (5A, D, E) and marsupial mancas (5B, C, F) of Porcellio scaber (ultrathin cross-sections). The newly forming cuticle in marsupial mancas, consisting of the epicuticle and pre-ecdysal procuticle, was mechanically connected to tendon cells. Numerous bundles of fibers (arrows) running from tendon cells through the new cuticle and ecdysal space into the detached cuticle are evident. Microtubules were found in close proximity to electron dense plaques at the apical surface of tendon cells.
