Aim of this study was to establish an experimental model in the mouse to investigate prefabricated neovascularization of Tissue Engineered Constructs, which presents a technically simple, timesparing and affordable alternative to various existing models. Neovascularization of two different vessel configurations was investigated as a function of time: a polyurethane sponge was wrapped around the femoral vessel of the mice and isolated with silicone foil. On the one hand, the vessel bundle was left as an axial flow through, on the other hand the vessel bundle was ligated beyond the construct. In a second experimental step implants colonized with human or bovine chondrocytes were prefabricated along a flow through pedicle. Analysis was done macroscopically and microscopically in terms of neovascularization and cell morphometry. Results were compared to the data from the literature, respectively to own results of former investigations. Ultimately it was able to proof, the investigated model represents a simplified, but valid experimental alternative.
