UPM, a Finnish different power and product enterprise, has launched a range of bioinks identified as GrowInk, designed for a variety of 3D bioprinting apps these kinds of as tissue engineering and regenerative drugs.
The GrowInk variety features novel non-animal derived hydrogels that emulate the in vivo environment to guidance cell expansion and differentiation. The materials debuted at the SLAS2020 science conference in San Diego, California.
Eco-welcoming 3D bioprinting materials
Launched in 1996, UPM develops and materials sustainable wooden-centered biomedical products and solutions. Its GrowDex line contains hydrogels for 3D cell culturing and investigate. In 2018, the company launched a recyclable biocomposite filament for FDM 3D printers, UPM Formi 3D, which works by using cellulose fibers and biopolymers. Last calendar year, the biotechnology organization and it is subsidiary, UPM Biocomposites, as effectively as robotics manufacturer ABB and Prenta Oy, collaborated to develop huge components and furniture utilizing its recyclable UPM Formi filament.
According to UPM, the two main components of its most current bioinks, GrowInk, are its nanofibrillar cellulose and h2o. This is integrated to present a described matrix that can be immediately blended with cells and tailored. A sterile hydrogel recognised as GrowDex-A has also been released. This hydrogel is intended to bind biotinylated molecules together with proteins, peptides, and antibiotics for 3D mobile culture.
GrowInks for health-related study
Presently, the GrowInk materials are out there in three versions. The initial, GrowInk-N is a natural opaque bioink created of pure nanofibrillar cellulose. GrowInk-T, a transparent, anionic nanofibrillar cellulose bioink for superior apps that can be optionally cross-connected to harden printed constructions. Eventually, GrowInk-ALG a nanofibrillar cellulose-primarily based bioink with alginate that can be cross-connected.
