Technology

Designed for human tissues. Built for clinical translation.

Glue4Life is a family of fully animal-free, hyaluronic acid-based hydrogels and bioinks developed for human tissue engineering, 3D bioprinting and biofabrication. Designed for engineering human soft tissues, the materials are biodegradable, chemically defined, soft and elastic, and suitable for printing, injection and pipetting — with no additional crosslinking required.
