Abstract
Our musculoskeletal system has a limited capacity for repair. This has led to increased interest in the development of tissue engineering strategies for the regeneration of musculoskeletal tissues such as bone, ligament, tendon, meniscus and articular cartilage. This talk will review our attempts to use biomaterials and mesenchymal stem cells (MSCs) to bioprint functional articular cartilage and bone grafts for use in bone and joint regeneration. It will begin by describing how 3D bioprinting can be used to engineer biological implants mimicking the shape of specific bones, and how these bioprinted tissues mature into functional bone organs upon implantation into the body. Next, it will be demonstrated that different musculoskeletal injuries can be regenerated using 3D bioprinted implants, including large bone defects and osteochondral defects. The talk will conclude by describing how we can integrate biomaterials and MSCs into 3D bioprinting systems to engineer scaled-up tissues that could potentially be used regenerate entire diseased joints.
