The primary goal of this research work was to establish the non-viral gene transfer with the plasmid of BMP-2 out of a biodegradable surface. In the first step, a metallic surface coating method was developed and tested in vitro.
For this surface coating method, a modified homogenizor was designed and after seeding with cells the expression rate was compared with a conventional homogenizor.
The COPROGsLuciferase were disperged with Poly-D-/-L-Lactid in a conventional glass homogenizor respective in the modified homogenizer and then coated onto alloy foils.
In the second part of the thesis, BMP-2 was complexed with Polyethylenimin and then covered by the Polyethylenglycol Copolymer (P6YE5C).
These particles were incorporated into a biodegradable Poly-D-/-L-Lactid (Resomer R203®) under aseptic conditions. In a cold coating technique titanium foils were then covered with DNA/R203 concentrations each.
In vitro tests with 293 cells showed an expression dependency upon the DNABMP-2/R203 concentration. An expression was detectable over a period of 14 days.
