Zusammenfassung der Projektergebnisse

During the DFG Fellowship we were able to bring evidence of the suitability of the use of PEO-PPO-PEO copolymers as new efficient delivery systems of therapeutic (TGF-β, SOX9) rAAV-2 vectors as an improved means to durably and safely modify hMSCs and human articular chondrocytes relative to free vector treatments with enhanced chondrogenic features relevant of the processes of cartilage repair. This fact highlights the potential of combining adapting tissue engineering platforms to gene transfer approaches mediated by rAAV vectors as an attractive tool to circumvent the natural obstacles from these clinically adapted vectors to achieve an efficient and durable gene expression of the therapeutic sequences within the lesions.
