Freeze-fracture characterization of the cuticle of adult and dauer forms of Caenorhabditis elegans.
At the ultrastructural level, a trilaminate structure, designated as the epicuticle, is always present on the outermost surface of the nematode Caenorhabditis elegans. The freeze-fracture technique revealed the existence of two fracture faces: an inner face that showed homogeneously distributed particles and an outer fracture face that was almost completely smooth in adult nematodes but appeared delicately granular in the dauer forms.
