Cells in the body are organised in tissues that are held together th rough a variety of molecular interactions. On the one hand, cells interact with each other. This is a very specific interaction mediated by various families of adhesion molecules called cadherins, neural cell adhesion molecules and intercellular cell adhesion molecules. These are all expressed on the surfaces of cells and anchored in the cytoskeleton of each cell, an arrangement which stabilises and gives strength to interactions between cells.
