The Saga of integrins: Integrin iigands. More than one integrin receptor (integrin) can recognize a specific ECM ligand, and more than one ligand can bind a specific integrin. Depicted are Viking ships representing ECM proteins that have been localized to implantation sites in mammals carrying shields representing integrins that potentially bind to these proteins
