Cell Adhesion and Migration

The architecture of many tissues is characterised by the adhesion of similar cells. One or more of the cell-adhesion molecules usually initiates cell adhesion to one another. Specialized junctions consisting of clustered cell-adhesion molecules are required for cells in tissues to behave in an integrated manner. Cell adhesion is a dynamic process that is most noticeable when non-adhesive cells become adhesive quickly. The polarity and physiological function of cells inside tissues are determined by cell–cell adhesion. Adhesion molecules on every cell facilitate interactions with other cells and the extracellular matrix in the cell microenvironment.

The purposeful movement of a single cell or a group of cells in response to chemical and/or mechanical signals is known as cell migration. It is a basic biological function that happens throughout life, beginning during embryonic development and lasting until death, and it can sometimes lead to disease pathogenic conditions. Cell migration is a crucial process that occurs during all of a complex organism's main developmental stages, resulting in the exact arrangement of cells, the creation of the nervous system, and the generation of specialized organs and tissues.
