"Efficient and controlled gene delivery from biodegradable materials can be employed to stimulate cellular processes that lead to tissue regeneration. In this report, a substrate-mediated approach was developed to deliver DNA from hyaluronic acid-collagen hydrogels. The hydrogels were formed by crosslinking HA with poly(ethylene glycol) diglycidyl ether," researchers in the United States report.
"Poly(ethylene imine)(PEI)/ DNA complexes were immobilized to the substrate using either biotin/neutravidin or non-specific adsorption. Complexes were formed in the presence or absence...
