Cell adhesion is an important process for cell division/ differentiation given that it heavily influences the polarity and physiological functions of cells, particularly within tissues. Through cell adhesion (cell-to-cell adhesion and cell adhesion to the extracellular matrix etc), cells become part of a microenvironment that consists of other cells and the extracellular matrix.

Cell– cell adhesion helps shape tissue organization during morphogenesis and preserves tissue cohesion in post-developmental life. In doing so, cell adhesion molecules influence diverse cellular processes, including cell–cell cohesion, recognition, signaling, and the regulation of cell proliferation.
Cell adhesion is crucial for the assembly of individual cells into the three-dimensional tissues of animals. Cells do not simply “stick” together to form tissues, but rather are organized into very diverse and highly distinctive patterns. A variety of cell adhesion mechanisms are responsible for assembling cells together and, along with their connections to the internal cytoskeleton.
