Printing spatially and temporally defined boundaries to direct the self-organization of cells and cellular aggregates to engineer functional tissues

Project description

Using bioprinted tissue to prevent osteoarthritis

Musculoskeletal disorders like osteoarthritis – a degenerative condition affecting millions of people worldwide – are the most common causes of chronic pain, disability and morbidity. Current treatments are limited in their efficacy. While musculoskeletal regeneration has become a prominent research area, regenerative strategies have failed so far to produce tissues mimicking the exquisite structural complexity of native tissues, dramatically limiting their clinical utility. In this context, the EU-funded 4D-BOUNDARIES project will use 3D bioprinting technologies to engineer, for the first time, patient-specific cartilage and meniscal grafts that mimic the internal and external anatomy and anisotropic mechanical properties of the native tissues. In the case of osteoarthritis, the ability to bioprint such functional tissues could prevent its development.

Objective

Regeneration of musculoskeletal tissues requires engineered grafts that mimic the heterogeneous and anisotropic structure and mechanics of the native tissue. Despite decades of research, existing regenerative strategies have failed to produce tissues mimicking this exquisite structural complexity, dramatically limiting their clinical utility. Clues to addressing this grand challenge can be found in normal tissue development, which relies upon both the self-organizing potential of stem cells as well as key physical instructions from the microenvironment to establish final tissue architectures. Recognising this, the goal of 4D-BOUNDARIES is to leverage emerging 3D bioprinting technologies to provide precise physical boundary conditions and spatially localised morphogens to self-organizing cells and cellular aggregates to engineer structurally anisotropic and mechanically functional musculoskeletal tissues. To realise this goal, 4D-BOUNDARIES will build upon applicant’s extensive expertise in bioprinting and bioink development to produce two new biofabrication platforms that provide temporary guiding structures to self-organizing tissues. To demonstrate the utility of these bioprinting platforms they will be used to engineer, for the first time, patient-specific cartilage and meniscal grafts that mimic the internal and external anatomy and anisotropic mechanical properties of the native tissues. The ability to bioprint such functional tissues will transform the field of orthopaedic medicine, providing grafts to biologically resurface large areas of damaged articular cartilage and meniscus and thereby prevent the development of osteoarthritis – a debilitating disease affecting millions of people worldwide. The impact of 4D-BOUNDARIES will not be limited to the orthopaedic space, as it is envisioned that these new bioprinting platforms will find numerous applications in tissue engineering and regenerative medicine.
