| pubmed-article:17997482 | pubmed:abstractText | Sustained release of functional plasmid DNA from the surfaces of materials which support cell adhesion for tissue formation could have a significant impact on gene therapy and tissue engineering. We report here layer-by-layer assembled multilayer film from a degradable cationic poly(2-aminoethyl propylene phosphate) and plasmid DNA encoding for enhanced green fluorescent protein (EGFP) for mouse osteoblast cell adhesion and prolonged gene delivery. Multilayer film growth was monitored by UV spectrophotometry and intensity of absorbance at 260 nm related to incorporated DNA increased in an exponential manner with increase the number of deposited polymer and plasmid layers. It degraded upon incubation in phosphate-buffered saline (PBS) at 37 degrees C and sustained the release of bioactive plasmid DNA up to 2 months. The multilayer film facilitated initial mouse osteoblast cell adhesion onto the surface and enhanced cellular alkaline phosphatase activity and calcium accumulation. It sustained delivering transcriptional active DNA to mouse osteoblast cells cultured on the film, and directly prolonged gene expression in the presence of serum without any exogenous transfection agent. This biodegradable multilayer assembly is promising for the local and sustained delivery of plasmid DNA and such a layer-by-layer system suggests an alternative method for plasmid DNA incorporation which may be useful for surface modification of implanted materials or scaffold for gene therapy and tissue regeneration. | lld:pubmed |
