Welcome to the 2013 annual report of the Trinity Centre for Bioengineering

(TCBE). Established in 2002, the TCBE brings together Principal Investigators,

research fellows, postgraduate students and undergraduate students from the

School of Engineering, the School of Medicine, the School of Dental Science and

the School of Natural Sciences in Trinity College Dublin (TCD), as well as

colleagues from the Royal College of Surgeons in Ireland (RCSI), University College

Dublin (UCD) and Dublin City University (DCU). The aim of the Centre is to promote and facilitate

research and education in Bioengineering in Bioengineering and related disciplines, and to ensure

this research finds its way into the clinic in order to improve patient care.

This annual report gives an overview of the TCBE’s core personnel and our key research and

educational activities over the 2013 calendar year. TCBE researchers work across five different

research themes: Musculoskeletal Research, Biomaterials, Regenerative Medicine, Cardiovascular

Research and Neural Engineering. This report demonstrates the impact that TCBE researchers are

making in these fields and beyond. This can be measured in many ways, from publications in

leading journals to the development of new products and the establishment of spin-out

companies. For example, 2013 has seen further growth in the number of peer-reviewed papers

published with over 85 papers published by TCBE researchers in the calendar year (source:

scopus). Citations to TCBE papers also increased to over 1800 in 2013 (excluding self-citations). In a

challenging funding environment, this is a remarkable achievement.

I would like to highlight just a small number of our achievements from the past year.

2013 saw TCBE PIs continue to attract grant funding from numerous different sources, further

details of which are available in this report. Of note was Dr. Garry Duffy’s €8.7 million EU FP7

project ‘Advanced Materials for Cardiac Regeneration’ (AMCARE). The aim of this project is to

develop natural materials and new surgical devices to enhance the delivery of the body's own

stem cells to the heart to promote healing after a heart attack (myocardial infarction) and

prevent premature death.

The new AMBER (Advanced Materials and BioEngineering Research) Research Centre, funded

by 19 Industry partners and Science Foundation Ireland (SFI), was officially launched on the

24th of October 2013 in Croke Park, Dublin. Further details are available in the report.

Collaborating Countries TCBE publications are co-authored with researchers from 35 countries worldwide

In January we hosted the 19th Annual Conference of the Bioengineering Section of the Royal

Academy of Medicine in Ireland (RAMI) in Johnstown House Hotel, Co. Meath. Nearly 200

delegates attended the conference. Prof. Richard Reilly delivered the Samuel Haughton lecture for

which he received the RAMI silver medal.

Two new PIs joined the Centre in 2013 - Prof Sally-Ann Cryan from the School of Pharmacy in the

Royal College of Surgeons in Ireland and Prof Martin Burke from the Department of Electronic and

Electrical Engineering in Trinity College Dublin. In addition, we have also had 15 new clinical PIs

join the Centre. These are clinicians who are already working closely with PIs in the TCBE – further

details can be found at http://www.tcd.ie/bioengineering/people/investigators/.

Fergal O’Brien and I submitted a successful bid to host the 2018 World Congress of Biomechanics

in Dublin. This conference takes place every 4 years, and we hope that it will attract over 3000

delegates to Ireland in 2018.

I hope you enjoy reading this report.

Kind Regards,

Prof. Daniel Kelly - Director of the Trinity Centre for Bioengineering

Crescent System® – Percutaneous Local Drug Delivery Prof Bruce Murphy and Dr Garrett Ryan have created the Crescent System®, a catheter based system designed to inject — directly and non-systemically — therapeutic agents safely through blood vessel walls into deep tissues. With this enabling technology, novel therapies can be developed and delivered site-specifically nearly anywhere in the body. These therapies may include treatments for renal denervation, plaque stabilization in diseased vessels, anti-tumor drugs, growth factors to stimulate cell division, and stem cell transplantation and gene therapies. Delivering drugs through the blood vessel wall into the perivascular space and adventitia allows for direct, highly controllable and concentrated treatment, minimizing the toxicity of systemic administration, while avoiding the “washing away” of drug into the bloodstream. This can reduce drug side effects, increase therapeutic effectiveness, potentially decrease the cost of medical treatment and improve patient quality of life

Crescent System – ‘Deflect and Inject’ technology platform The Crescent System has the following competitive advantages:

Control: The Micro-Infusion Catheter needle precisely targets an injection. Efficiency: Compounds are delivered to the outside of the vessel without systemic

washout. Safety: Unlike conventional infusion catheters with pressure jets or larger, unsheathed

needles, the Crescent System needle — with a width of only two human hairs — does not injure the vessel wall.

Feedback: Perivascular delivery is immediately visualized with minute amounts of contrast medium, proving positively that the drug is localized at the target.

Consistency: The Micro-Infusion Catheter provides the most repeatable dose control of any prior infusion-based catheter system.

Sizing: The Micro-Infusion Catheter provides a 1 size fits all from vessels ranging from 3-9mm in diameter, thereby reducing hospital inventory and cost.

Engineering zonal cartilage grafts

Engineering organs and tissues with the spatial composition and organisation of their native

equivalents remains a major challenge. One approach to engineer such spatial complexity is to

recapitulate the gradients in regulatory signals that during development and maturation are

believed to drive spatial changes in stem cell differentiation.

Mesenchymal stem cell (MSC) differentiation is known to be influenced by both soluble factors and

mechanical cues present in the local microenvironment. The objective of this study was to engineer

a cartilaginous tissue with a native zonal composition by modulating both the oxygen tension and

mechanical environment thorough the depth of MSC seeded hydrogels. To this end, constructs were

radially confined to half their thickness and subjected to dynamic compression (DC). Confinement

reduced oxygen levels in the bottom of the construct (see Fig 1) and with the application of DC,

increased strains across the top of the construct. These spatial changes correlated with increased

glycosaminoglycan accumulation in the bottom of constructs, increased collagen accumulation in

the top of constructs, and a suppression of hypertrophy and calcification throughout the construct

(see Fig 1). The combination of spatial confinement and DC was also found to increase

proteoglycan-4 (lubricin) deposition toward the top surface of these tissues. In conclusion, by

modulating the environment through the depth of developing constructs, it is possible to suppress

MSC endochondral progression and to engineer tissues with zonal gradients mimicking certain

aspects of articular cartilage.

This study was undertaken in Dr. Daniel Kelly’s lab and was published in PLoS One.

Orchestrating osteogenic differentiation of mesenchymal stem cells

The bones in our body have an inherent capacity to respond to mechanical loading. For example,

astronauts subjected to long term periods of weightlessness in microgravity lose bone mass due to

underloading while the dominant serving arms of professional tennis players gain mass due to excess

loading. The work in this article sought to gain a greater understanding of the mechanisms involved

that cause cells to respond to mechanical loading. Mesenchymal Stem Cells (MSC) were grown on a

highly porous collagen scaffold to present the cells with an environment more representative of the 3D

native tissue than typical 2D petri dishes (Fig. 2). These cell-seeded scaffolds were then subjected to

mechanical loading through the application of fluid flow using a flow perfusion bioreactor (Fig. 3).

Advanced gene array technologies were subsequently employed to initially screen over 24,000 genes

in an effort to identify those that were altered as a result of mechanically loading. Genes which

demonstrated large changes following stimulation were shortlisted for further analysis. Placental

Growth Factor (PGF), known to have involvement in fracture repair but not until now linked to

mechanosensitivity, was one such gene that exhibited a greatly increased level of expression in

response to the applied flow conditions and was selected for further evaluation. We demonstrated

that PGF expression levels correlated to both the magnitude and duration of flow exposure. By then

applying recombinant versions of this protein to different cell types, the study demonstrated a clear

concentration-dependant response with respect to 3 keys phases of bone physiology; vascularisation,

resorption and bone formation (osteogenesis). Lower PGF concentrations had the strongest pro-

osteogenic effect, whilst higher concentrations favoured vascularisation and bone resorption. This

work has helped to expand the knowledge space pertaining to the mechanical regulation of bone

formation and remodelling, whilst also providing a novel therapeutic target for further study with

respect to enhancing bone regeneration in clinical applications. This study was undertaken in Prof.

Fergal O’Brien’s lab and was published in Stem Cells.

Shape memory scaffolds for minimal invasive surgery Dr. Buckley’s team published their recent work in Acta Biomaterialia on developing porous alginate scaffolds with shape-memory properties. These materials can be delivered using minimally invasive approaches and recover to their original geometry once hydrated. Covalently cross-linked alginate hydrogels were created using carbodiimide chemistry, followed by a freeze-drying step to impart porosity. Results showed that porous alginate scaffolds exhibited shape-memory recovery and can be repeatedly compressed and expanded, which provides the potential to deliver the biomaterial directly to the damaged tissues.

Biomaterials research in the TCBE spans many biomedical application areas. Projects carried out

during 2013 involved shape memory scaffolds for minimal invasive surgery and decellularised

scaffolds for peripheral nerve regeneration

Regenerative Medicine

Decellularised scaffolds for peripheral nerve regeneration MSc Bioengineering student Rukmani Sridharan was awarded "Best overall MSc Thesis in Bioengineering 2013" for her work entitled "Freeze dried, acellular nerve scaffolds with longitudinal channels for peripheral nerve regeneration". This research was a collaborative project between the groups of Dr. Buckley and Prof. Reilly. This work modified a previously developed decellularization protocol to improve cellular removal while preserving matrix structure in rat sciatic nerve sections and introduced longitudinal oriented channels, 20-60µm (diameter) using a unidirectional freeze-drying process. This study represents the first attempt to modify the physical structure of decellularized nerves to enhance cell penetration which may serve as a basis for future peripheral nerve regenerative strategies using acellular allografts.

The Trinity Centre for Bioengineering research programme is focused on an integrated programme

investigating the full hierarchy of the body’s biomechanical and bioelectric systems from cell to tissue to organ

along with their interaction with medical devices. Our team of Principal Investigators, postdoctoral fellows,

PhD students and M.Sc. students work in collaboration with twelve hospitals, leading medical device

companies, national and international research centres and universities. This integrated approach is centred

around five specialisations:

Musculoskeletal ● Biomaterials ● Cardiovascular ● Regenerative medicine ● Neural engineering

Research in these areas is based on the intersection of biomedical science and engineering and forms the

foundation for enabling technologies for advances in key areas of active and passive implantable devices,

surgical and medical device design, as well as informing clinical studies and interventions in ageing,

neurodegeneration and rehabilitation.

Theme 1: Cell response to biochemical and biophysical stimulation in 3D matrices. The

functionality of cells from both healthy, ageing, and osteoarthritic patients are being

studied, and markers for skeletal diseases are being identified.

Theme 2: The development of novel tissue engineering and regenerative medicine

strategies for tissue and organ regeneration, with a specific focus on orthopaedic and

cardiovascular medicine. Novel biomaterial scaffolds and bioreactors are being

developed for this purpose, supported by the use of computational tools to optimise

the design of such regenerative strategies.

Theme 3: Reconstruction of human function requires an engineering approach through

musculo-skeletal modelling to simulate functional requirements and for the

development of prototype devices for trials in patients. Along with the Trinity College

Institute for Neuroscience, neural engineering research focuses on new brain imaging

methodologies and in-vivo recordings of specific circuits to provide an understanding of

neural mechanisms of behaviour, together with electrical stimulation based

treatments.

Theme 4: is titled “Frontiers in Medical Device Design” and will focus on controlling

cells to perform defined functions as part of the medical device. In silico methods will

be used predominantly to model new concepts in cardiovascular, orthopaedic and

neural implant design.
