Gelma as innovative as your research Banner


It has a much lower antigenicity compared to similar collagen-based bioinks because of its arginine-glycine-aspartic acid (RGD) peptide sequence. This tripeptide sequence promotes cellular growth increasing cellular viability when cells are incorporated.


GelMA contains matrix metalloproteinase (MMP) degradable motifs which are enzyme binding locations that trigger the catabolism of the gelatin architecture in GelMA. The degradation of GelMA is then replaced by the natural ECM without triggering a severe inflammatory response.

Naturally Derived

GelMA contains a gelatin protein base derived from naturally occurring sources.
