Cells grew faster with MatrigelTM (a gelatinous protein mixture secreted by Engelbreth-Holm-Swarm mouse sarcoma cells) than with any other single adhesion molecule presumably because Matrigel TM resembles the complex extracellular environment found in many tissues that contains multiple species of adhesion molecules (Laminin, Entactin, and Collagen) and growth factors as well as other components. Here, NID1 is linked to sarcoma.
