Scaffold-guided gene transfer offers strong systems to develop noninvasive convenient therapeutic options for the treatment of articular cartilage defects, especially when targeting bone marrow aspirates from patients containing chondroregenerative mesenchymal stromal cells in a native microenvironment. In this study, we
