  abstract  = {A major therapeutic challenge is the increasing incidence of chronic disorders. The persistent impairment or loss of tissue function requires constitutive on-demand drug availability optimally achieved by a drug delivery system ideally directly connected to the blood circulation of the patient. However, despite the efforts and achievements in cell-based therapies and the generation of complex and customized cell-specific microenvironments, the generation of functional tissue is still unaccomplished. This study demonstrates the capability to generate a vascularized platform technology to potentially overcome the supply restraints for graft development and clinical application with immediate anastomosis to the blood circulation. The ability to decellularize segments of the rat intestine while preserving the ECM for subsequent reendothelialization was proven. The reestablishment of a functional arteriovenous perfusion circuit enabled the supply of co-cultured cells capable to replace the function of damaged tissue or to serve as a drug delivery system. During in vitro studies, the applicability of the developed miniaturized biological vascularized scaffold (mBioVaSc-TERM®) was demonstrated. While indicating promising results in short term in vivo studies, long term implantations revealed current limitations for the translation into clinical application. The gained insights will impact further improvements of quality and performance of this promising platform technology for future regenerative therapies.},
