Cell junction
A
cell junction
(or
intercellular bridge
) is a type of structure that exists within the
tissue
of some
multicellular organisms
, such as
animals
. Cell junctions consist of
multiprotein complexes
that provide contact between neighbouring
cells
or between a cell and the
extracellular matrix
. They also build up the paracellular barrier of epithelia and control the
paracellular transport
. Cell junctions are especially abundant in
epithelial
tissues.
