Maintaining the zonula adherens junction, the cell-cell adherens junction formed near the apex of epithelial cells.

The aggregation, arrangement and bonding together of a set of components to form a pore complex. A pore complex is a small opening in a membrane that allows the passage of liquids and/or gases.

The attachment of an epithelial cell to another epithelial cell via adhesion molecules.

Any process that modulates the frequency, rate or extent of heart contraction. Heart contraction is the process in which the heart decreases in volume in a characteristic way to propel blood through the body.

The attachment of one cell to another cell via a cadherin, transmembrane proteins having repeating extracellular calcium ion binding domains.

The attachment of one cell to another cell via a cadherin, transmembrane proteins having repeating extracellular calcium ion binding domains.

Maintaining the zonula adherens junction, the cell-cell adherens junction formed near the apex of epithelial cells.

Maintaining the zonula adherens junction, the cell-cell adherens junction formed near the apex of epithelial cells.

The process in which a cardiac muscle precursor cell acquires specialized features of a cardiac muscle cell. Cardiac muscle cells are striated muscle cells that are responsible for heart contraction.

The attachment of an epithelial cell to another epithelial cell via adhesion molecules.

The attachment of an epithelial cell to another epithelial cell via adhesion molecules.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

A structure comprised of a core structure (in most organisms, a pair of centrioles) and peripheral material from which a microtubule-based structure, such as a spindle apparatus, is organized. Centrosomes occur close to the nucleus during interphase in many eukaryotic cells, though in animal cells it changes continually during the cell-division cycle.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

A cell-cell adherens junction which forms a continuous belt near the apex of epithelial cells.

A cellular component that forms a specialized region of connection between two or more cells or between a cell and the extracellular matrix. At a cell junction, anchoring proteins extend through the plasma membrane to link cytoskeletal proteins in one cell to cytoskeletal proteins in neighboring cells or to proteins in the extracellular matrix.

Any small opening in a membrane that allows the passage of gases and/or liquids.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

A cell junction that forms a connection between two or more cells in a multicellular organism; excludes direct cytoplasmic junctions such as ring canals.

A cell-cell adherens junction which forms a continuous belt near the apex of epithelial cells.

A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
