Cellular Adhesion Molecules (CAMs) are proteins located on the cell surface involved in the binding with other cells or with the extracellular matrix (ECM). These molecules play a crucial role in maintaining the structural integrity of tissues and facilitating various physiological processes such as cell signaling, growth, and differentiation. CAMs are essential in the context of Histology because they help to elucidate the interactions between cells and their microenvironment.
