23 Jul Drug/factor control-released thin film scaffold and preparation method thereof
Abstract
The invention provides a drug/factor control-released thin film scaffold. The drug/factor control-released thin film scaffold is characterized by comprising a film-like bionic scaffold, a PDGF (Platelet Derived Growth Factor) coating layer and a slow release layer which are sequentially arranged. According to a scaffold material, i.e, a film-like scaffold material on the surface layer of a factor/the core layer of a drug, for clinic periodontal treatment, provided by the invention, controlled release of active factors and drugs is realized, and cell proliferation and osteogenic differentiation are promoted, so that three elements of seed cells, a scaffold material and regulatory factors in tissue regeneration are organically combined, periodontal repairing is promoted, and a facilitation function for periodontal tissue engineering research is obtained.
