Biofabrication of gene activated grafts targeting synovial joint inflammation and meniscus repair

Objective

Each year an estimated 1.5 million meniscal repair surgeries are performed in the United States and Europe, making this one of the most common procedures in orthopaedics. Current clinical management involves partial or total removal of the damaged tissue, increasing osteoarthritis (OA) risk 14-fold. Conventional meniscal tissue engineering strategies have failed to recapitulate the structure, composition and cellular complexity of the native meniscus, limiting clinical translation. Moreover, they rarely address the inflammatory synovial microenvironment accompanying meniscal lesions, a key factor that impedes healing and accelerates OA progression. SMART-MENISCUS aims to develop the first genetically modified, zonally defined meniscal graft that recapitulates the complexity of the native meniscus while actively targeting synovial inflammation. The project is structured into three interconnected aims addressing the biological complexity and translational challenges of meniscus regeneration. Aim 1 will test whether human mesenchymal stem cell-derived microtissues can be 3D bioprinted into melt-electrowritten (MEW) scaffolds to generate anisotropic grafts with defined collagen architecture and load-bearing capacity and evaluate their resistance to inflammatory degradation under dynamic loading. Aim 2 will focus on the development of gene-activated constructs by integrating microRNA-loaded nanoparticles in the MEW scaffolds to control gene expression, drive regeneration and modulate post-injury inflammation. Finally, Aim 3 will engineer autologous, gene-activated, scaled-up meniscus grafts and validate their regenerative efficacy and immunomodulatory potential in a large animal model. SMART-MENISCUS will improve recovery after meniscus injuries, reduce OA risk, and minimize the need for costly medical interventions. This project will enhance functional meniscus regeneration and the quality of life for millions affected by meniscal damage and synovial joint degeneration.
