Laminins are proteins composed of three subunits — α-chain, β-chain and γ-chain. They are a major component of the basal lamina lining a cell membrane’s external surface. Its cross-like structure serves as the foundation for many tissues. Laminins play an important role in cell differentiation, migration, adhesion and the support of healthy tissue.

CELLINK LAMININK 521 is an enhanced formulation of our CELLINK Bioink that supports different tissues types, including pluripotent and embryonic stem cells and induces their self-renewal. Laminin 521 supports many cell types, including cells from pancreas, vascular, nervous and muscular systems. The bioink can be used as a base material for specialized cells including hepatocytes, cardiomyocytes and neurons offering excellent printability and easy crosslinking, and is a great starting point for culturing many cell types in 3D. Also available with a GelXA base.
