Laminin’s essential role in cell differentiation, migration and adhesion can now be found in a stable, easy-to-use bioink. GelXA LAMININK 121 can be utilized with several cell types and this bioink can be utilized as a great starting point for the culture of many cell types. Laminin 121 is widely expressed during embryonic and early development of the lining of tissues and organs. This laminin variation is also found predominantly in the placenta, skeletal muscle, and kidney tissue. GelXA LAMININK 121 is particularly suitable as a base material for the culture of several cell types, including skeletal muscle, brain, kidney and liver cells. GelXA LAMININK 121 can be printed at room temperature and crosslinked with both UV and ionic crosslinking agent thanks to the addition of alginate.
