Laminin is a critical component of the extracellular matrix (ECM), a complex network of proteins and other molecules that provide structural and biochemical support to cells. Laminin is a glycoprotein composed of three different chains (α, β, and γ) and plays a crucial role in cell differentiation, migration, adhesion, and stability. It is particularly abundant in basement membranes, which separate epithelial and endothelial cells from the underlying connective tissue.
