- basement membrane phenotype
Animals exhibit variations or abnormalities in the structure, integrity, function, or quality of basement membranes, compared to controls.
- basement membrane remodeling variant
Animals display variations in the manner in which the basement membrane (a thin, dense, sheet-like structure built on a network of polymeric laminin and type IV collagen) is remodeled, compared to control animals.
- basement membrane gap expansion variant
Animals display variations in the manner in which an opening in the basement membrane (a thin, dense, sheet-like structure built on a network of polymeric laminin and type IV collagen) expands to make way for intertissue connections, compared to control animals.
- marginal cell development variant
Any variation in the progression of a marginal cell over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell compared to control. A marginal cell is a pharyngeal cell that connects the basement membrane to the apices of the triangle-shaped pharyngeal lumen.
- anchor cell invasion variant
Any variation in the process by which the gonad anchor cell makes contact with vulval cells in order to create a uterine-vulval connection. In C. elegans, this includes the loss of the basement membranes between these cells and the crossing of the basolateral portion of the anchor cell through this gap.
- body wall muscle cell polarization variant
Variations in the accumulation of muscle proteins at membranes where adjacent muscle cells contact each other and the hypodermis compared to control. In C. elegans, during early embryonic body wall muscle development, muscle, basement membrane, and hypodermal components are all colocalized in a continuous linear structure at the site of muscle-hypodermal contact.
