Resumo
The main goal of this thesis has been the development, optimization, and testing of three-dimensional mRNA-activated matrices as a system for the administration of transcription factors for articular cartilage regeneration. Modifications in the mRNA synthesis provided higher stability and efficacy as compared to standard mRNA. TAMs chondrogenic effects were tested in 3D cultures activated with SOX9, TGF-β3 or combinations of both. The transcript combination provided the best effects as it combined the strong chondrogenic effect of TGF-β3 with the capacity of SOX9 to promote chondroblast differentiation while inhibiting fibrotic tissue formation. The two best TAM prototypes were studied in a cartilage defect rabbit model where showed no signs of toxicity and promoted the expression of specific tissue markers.
