Novel Hydrogels Invented For Repairing, Regenerating Human Tissue ScienceDaily 7/20/07 "...scientists have invented a novel biomaterial with surprising antibacterial properties that can be injected as a low-viscosity gel into a wound where it rigidifies nearly on contact--opening the door to the possibility of delivering a targeted payload of cells and antibiotics to repair the damaged tissue...Regenerating healthy tissue in a cancer-ridden liver, healing a biopsy site and providing wounded soldiers in battle with pain-killing, infection-fighting medical treatment are among the myriad uses the scientists foresee for the new technology...Hydrogels are formed from networks of super-absorbent, chain-like polymers. Although they are not soluble in water, they soak up large amounts of it, and their porous structure allows nutrients and cell wastes to pass right through them...Schneider and Pochan and their research teams have been focusing on developing peptide-based hydrogels that, once implanted in the human body, will become scaffolds for cells to hold onto and grow--cells such as fibroblasts, which form connective tissue, and osteoblasts, which form bone."
