TissueFab® GelMA based bioink for 3D bioprinting applications

Gelatin methacryloyl (GelMA), derived from natural extracellular matrix (ECM) components, is a polymerizable hydrogel material. Its abundance, low cost, and retention of natural cell binding motifs, makes it a highly desirable material that is sought for tissue engineering applications. 

Photocrosslinkable methacrylamide functional groups have been added to GelMA, which allows for the synthesis of biodegradable, biocompatible, and non-immunogenic hydrogels that are stable in biologically relevant conditions whilst promoting cell adhesion, spreading, and proliferation.

Temporal and spatial control of the crosslinking reaction can be obtained by adjusting the degree of functionalization and polymerization conditions, allowing for the fabrication of hydrogels with unique 3D structures, patterns, and morphologies.
