- Scientists in Sweden developed a 'skin in a syringe' gel containing live cells for wound healing.
- The gel can be 3D-printed into skin grafts to help the body build functional dermis instead of scar tissue.
- The innovation combines fibroblast cells on gelatin beads with a hyaluronic acid gel using click chemistry.
- The gel becomes liquid under light pressure, allowing syringe application, then reverts to gel form.
- Tests on mice showed cell survival, new dermis production, and blood vessel formation in the grafts.
- Researchers also created elastic hydrogel threads for perfusable channels, aiding artificial tissue and organoid development.
- The technology could revolutionize burn treatment by minimizing scarring and improving skin regeneration.
