Development of micro-incubator OCT, OCE bioreactor system to engineer a robust musculoskeletal tissue model

Achieving adequate musculoskeletal tissue healing is one of the most challenging factors in the repair of orthopaedic tissues. This Development of micro-incubator OCT, OCE bioreactor system to engineer a robust musculoskeletal tissue model project is offered at University of Dundee

This Development of micro-incubator OCT, OCE bioreactor system to engineer a robust musculoskeletal tissue model project at University of Dundee will explore how to develop a bioreactor system and optimise a stimulation regime to produce robust tissue-engineered models. The formation of tissue-engineered constructs will be approached using a fibrin-gel contraction model with bone anchor regions, mimicking native tissue interfaces. An innovative co-culture system will allow the production of a complete engineered interfaced construct and will endeavour to replicate the native tissue transitions found at the enthesis between tissue types in vivo. Complete tissue interface grafts will then undergo stretching regimes to aid tissue maturation. The maturation process will be qualitatively and quantitatively analysed by using Optical Coherence Tomography (OCT) and Elastography (OCE) in the modular bioreactor system.

Context

Achieving adequate musculoskeletal tissue healing is one of the most challenging factors in the repair of orthopaedic tissues. The problem of hard-to-soft tissue fixation is the major cause of failure of replacement grafts and leads to further musculoskeletal degeneration e.g. osteoarthritis.

Development of this novel culture system will

• contribute to the knowledge regarding interface formation, optimum growth and stimulation requirements
• provide a robust model to investigate enthesisal healing and repair.
