TissueFab® GelAlg LAP Bioink for 3D bioprinting applications

A polymerizable hydrogel material made of natural extracellular matrix (ECM) components is called gelatin methacryloyl (GelMA). Gelatin has become a widely sought-after substance for tissue engineering applications because of its low cost, availability, and preservation of natural cell-binding patterns.

Alginate is a naturally occurring polymer that is frequently used for bioprinting applications since it can readily be adjusted in terms of printability by changing the polymer density and crosslinking with calcium chloride (CaCl2). To promote cell adhesion and differentiation, alginate and gelatin are frequently mixed.

By altering the degree of functionalization and polymerization conditions, it is possible to regulate the crosslinking reaction’s timing and location, creating hydrogels with distinctive morphologies, 3D structures, and patterns.
