How Do Cellular Junctions Maintain Tissue Cohesion?
Cellular junctions are specialized structures that connect cells to each other and to the ECM. These include tight junctions, adherens junctions, desmosomes, and gap junctions. Tight junctions create a barrier that regulates the passage of substances between cells, while adherens junctions and desmosomes provide mechanical linkage. Gap junctions allow for direct communication between cells, facilitating coordinated responses to stimuli.
