Liquid to gel to bone


Rice U. develops temperature-sensitive gelling scaffolds to regenerate craniofacial bone

Rice University bioengineers have developed a hydrogel scaffold for craniofacial bone tissue regeneration that starts as a liquid, solidifies into a gel in the body and liquefies again for removal.

The material developed in the Rice lab of bioengineer Antonios Mikos is a soluble liquid at room temperature that can be injected to the point of need. At body temperature, the material turns instantly into a gel to help direct the formation of new bone to replace that damaged by injury or disease.

The gel conforms to irregular three-dimensional spaces and provides a platform for functional and aesthetic tissue regeneration. It is intended as an alternative to prefabricated implantable scaffolds.
