GrowInk Bioinks for 3D printing

GrowInks are animal free, biocompatible, ready-to-use hydrogels that can be mixed directly with cells for bioprinting applications. The two main components in GrowInks are nanofibrillar cellulose and water, providing you with a fully defined matrix. The matrix can be customised by the addition of molecules, such as growth factors or adhesion proteins, as needed by your specific cells.

What does shear thinning mean?

UPM nanocellulose hydrogel is a temperature stable gel with shear thinning properties: its viscosity decreases under shear strain and it recovers back to its semisolid state when the applied stress is removed, enabling it to be used in various ways.

UPM GrowDex - biomedical innovation and climate action from sustainably managed forests

Climate change can be addressed in hundreds of ways: UPM's climate approach is built on sustainable forestry, resource efficient production and most of all responsible and renewable products made of wood fibres. We see that any step we take in any of these areas can be a remarkable climate action. This time we introduce UPM GrowDex, a unique nanofibrilar cellulose hydrogel for 3D cell culturing and other biomedical applications. It is a great example of UPM's Biofore Beyond Fossils commitment and showcases our ultimate goal to replace fossil-based materials whenever possible.


GrowDex – The cellulose based hydrogel for 3D cell culture

GrowDex is an animal-free, biocompatible and ready to use hydrogel that physically mimics the extracellular matrix (ECM). This bio-friendly and flexible innovation has been shown to support a variety of cell types cultured in 3D with consistent results.
