F12. Celle-celle og celle-ECM interaktioner Flashcards
Draw a sheet of epithelial cells has an apical and a basal surface
Show how adherens junctions form adhesion belts around epithelial cells in the samll intestine
Show how An integrin protein switches to an active conformation when it binds to molecules on either side of the plasma membrane
Show how Cadherin proteins mediate mechanical attachment of one cell to another.
Show how Cells can be packed together in different ways to form an epithelial sheet
Show how Collagen fibrils in the skin of some animals are arranged in a plywoodlike pattern
Show how Desmosomes link the keratin intermediate filaments of one epithelial cell to those of another.
Show how Different types of functionally polarized cell types line the intestine
Show how Epithelial sheets can end to form an epithelial tube or vesicle
Show how Extracellular signals can regulate the permeability of gap junctions
Show how Fibroblasts influence the alignment of collagen fibers
Show how Fibronectin and transmembrane integrin proteins help attach a cell to the extracellular matrix
Show how Gap junctions provide neighboring cells with a direct channel of intercytosolic communication
Show how Glycosaminoglycans (GAGs) are built from repeating disaccharide units
Show how Hemidesmosomes anchor the keratin filaments in an epithelial cell to the basal lamina
Show how Incorrect collagen assemly can cause the skin to be hyperextensible.
Show how Proteoglycans and GAGs can form large aggregates
Show how Several types of cell junctions are found in epithelia in animals
Show how The basal lamina supports a sheet of epithelial cells
Show how The cytoplasma of adjacent plant cells are connected via plasmodesmata.
Show how Tight junctions allow epithelial cell sheets to serve as barriers to solute diffusion
