The QM-Emulate Organs-on-Chips Centre provides access to Emulate’s Organs-on-Chips technology to enable researchers to develop organ models of their design to expedite their experiments. Expert staff are on hand to support with training and use of the platform as well as pushing forward new organ-on-a-chip research projects led by Knight and Screen. The Centre also provides opportunities for collaboration with Emulate and support for commercialisation and translational impact. The centre is part of the new Centre for Predictive in vitro Models (CPM). Visit the web site to see full details of this and the new Emulate centre: https://www.cpm.qmul.ac.uk/emulate/

The primary goal of this project is to establish how and where in tendon tendinopathy originates, and to define how the age-related changes in tendon accelerate progression to tendinopathy. Our goal is to identify the specific IFM changes that drive increased injury risk with ageing. This is exciting as we can then continue, in future studies, to develop treatments specifically aimed at preventing, reversing, or mitigating the effects of these changes.

Musculoskeletal diseases cause pain and suffering to millions of people worldwide. This proposal aims to significantly enhance our understanding of hypercholesterolemia on aspects of tendon health, a highly under-researched area and one of significant clinical importance. The findings from the proposed research are likely to have major implications for orthopedic sciences and preventative medicine as well as rehabilitation services, strategies and technology. Such knowledge has the potential to improve quality of life and reduce socio-economic costs associated with the disability resulting from orthopedic and musculoskeletal diseases.
Development of a synovium-chondrocyte organ-on-a-chip model with integrated biomechanical stimulationFunding source: EPSRC OA Tech Network plus Pump-Priming Project Grant
Start: 01-07-2019 / End: 31-12-2019
We plan to develop an organ-on-a chip microfluidic model to investigate the effects of mechanical stimulation on the interaction between musculoskeletal cells within the joint. This chip will incorporate the multiple cell types seen in cartilage and the surrounding synovial environment to mimic human tissue architecture, cellular microenvironment and signalling.
Measuring local strain distributions through the equine SDFT as a novel indicator of injury risk: effective injury management and preventionFunding source: Horserace Betting Levy Board
Start: 01-07-2016 / End: 10-05-2019
In this project we are developing novel uses of ultrasound imaging, to investigate the strains in the equine SDFT during use. We think that alterations in strain fields in the tendon occur during injury and by finding methods to measure these we can more easily manage tendon health
The inter-fascicular matrix mediates tendon fatigue resistance: Do age related changes lead to tendinopathy?Funding source: Arthritis Research UK
Start: 06-01-2014 / End: 05-06-2017
This project investigates three functionally distinct human tendons, in order to establish the differences in structure, composition and mechanics that facilitate tendon healthy function. This allows us to probe the key factors that lead to tendon injury and establish why some individuals have such injury prone tendons.
Start: 01-04-2015 / End: 31-03-2017
We are looking to understand the development of the interfascicular matrix (IFM) in the horse to establish how this critical structure develops. This opens up exciting opportunities to develop approaches, such as training or conditioning, to manage IFM development or repair from injury, to maintain tendon health
Start: 01-05-2013 / End: 11-11-2016
We have been showing how ageing influences the mechanics and function of the tendon matrix, particularly altering the interfascicular matrix. These changes are likely associated with the increased risk of tendon injury with ageing, providing insights into the process of tendon degeneration
Start: 01-10-2012 / End: 30-09-2015
This project focused on the effects of 10Hz loading on tendon cells, hypothesising improved tendon repair under such higher frequency loading. Data has demonstrated increased matrix turnover when tenocytes are exposed to loading at 10Hz relative to 1Hz
Start: 01-06-2012 / End: 31-05-2014
Investigating cell mechanotransduction requires a highly controlled cell environment within which the effects of mechanical stimuli can be characterised. This project developed a hydrogel scaffold material able to apply physiologically relevant strains to tenocytes and specifically investigated the effects of different peptides for cell attachment, their effects of integrin binding. We showed how altering the integrins linking cell and matrix influenced cell metabolism and matrix turnover.

Shockwave therapy has been reported to be successful in the treatment of tendinopathy. However, there is little information concerning how it may treat the condition. This project used microdialysis to investigate the cellular response to shockwave therapy in healthy and tendinopathic tendons, highlighting how the treatment initiates an inflammatory response, which may be critical for tendon repair

Some tendons work to store energy and release it during use, significantly improving the energetic cost of locomotion. There is currently little understanding of how these tendons function, but they are know to contain a small amount of elastin and our preliminary data suggests this is critical to tendon mechanics, This project investigates the organisation and function of elastin in tendon mechanical behaviour, hypothesising that it is ciritical for healthy tendon function.

Tendon is mechanosensitive, maintaining tissue health in response to applied loads. Overload is a key contributor to the development of tendon pathologies, know as tendinopathies; a range of highly debilitating and increasingly prevalent conditions2-3. However, the mechanisms associated with tendinopathy development remain unclear. Current evidence supports a combined mechanical ...
