Establishing human blood vessel organoids as a model for drug screening for Diabetes and Vascular Complications using the Remarkable technology of induced pluripotent stem cells
One of the most deleterious events in diabetes, at the levels of the micro- and macro- vasculature, is endothelial cell (EC) dysfunction and blood vessels damage. Blood vessels contribute to the development of essentially all organ systems and have critical roles in multiple diseases. In particular, major diabetic complications are the consequence of blood vessel pathologies, such as reduced capillary densities and thickening of the basement membrane, resulting in insufficient tissue oxygenation, impaired cell trafficking or vessel leakage. Diabetes not only impairs the functions of ECs, but also disturbs the communication between ECs and pericytes.
Having recently developed outstanding expertise to generate diabetic patient specific induced pluripotent stem (iPS) cells and differentiate them towards vascular cells such as ECs; we found that iPS-derived ECs (iPS-ECs) from diabetic donors carry an imprint of the diabetic milieu which is reflected in dysfunctional responses.
We will use iPS and we will differentiate them to ECs from diabetic donors as the system to analyse important pathogenic mechanisms and discover effective therapies for diabetes.
These patient-specific cells are now valuable tools to study the underlying causes and mechanisms of the pathogenesis of EC dysfunction and to move one step forward by generating human blood vessels organoids to set up diabetic human models to deliver new knowledge, biomarker of diabetes and effective therapies.
Human blood vessel organoids derived from iPS cells have recently been developed, containing ECs and pericytes that self-assemble into capillary networks. Shape https://d.adroll.com/cm/aol/out?advertisable=USYKOWLOFBEXPCZFZ62G6RGrown in a petri dish, these 3D models display a striking structural similarity and function to human blood vessels. In our lab, we have recently established the model of blood vessels organoids derived from non-diabetic and diabetic human donors, which contain ECs and pericytes that self-assemble into capillary networks that are enveloped by a basement membrane. These organoids derived from human iPS cells faithfully recapitulate the structure and function of human blood vessels and are amenable systems for modelling and serve as a valuable model of drug screening for diabetic vasculopathy, a disease that affects hundreds of millions of patients worldwide.
The proposed project will be completed within 3 years, and it will provide an excellent opportunity for an enthusiastic and highly motivated student to be training in the cutting-edge field of induced pluripotent stem cells technology of patient specific cell in a petri-dish. Training will also be provided in fundamental techniques in molecular biology such as RNA isolation and Real time PCR, protein extraction and western blot, confocal microscope, transfection experiments, luciferase reporter assays, in vitro and in vivo diabetic and vascular disease models. Key skills such as experimental design, data summary, critical thinking, analysis and interpretation of the results, presentation skills, scientific writing, will also be provided.

Whilst I’m a Belfast native, I didn’t complete my Bachelor’s or Master’s degree at Queen’s. However, after attending Universities in Leeds, Melbourne, Gothenburg and Shanghai, I decided it was time to return to my home city to undertake my PhD at the Centre for Public Health. Two years in and I’m so happy with my decision. I feel very supported and valued here and have had the opportunity to get involved in various things outside of my research which has allowed me to develop personally and has enriched my experience at Queen’s.
The School has current collaborative partnerships with the NIH National Cancer Institute (Washington) and the Princess Margaret Cancer Centre (Toronto), together with developing relationships with international institutions in the Middle East, such as Hashemite University (Zarqa, Jordan). In addition, some of our current students conduct the majority of their research abroad (currently US and China) with supervisors from both QUB and the external institution. The School also supports short-term research training opportunities for its postgraduate students in the groups of international collaborators; these enriching experiences not only benefit the project but provide valuable insight into research in a global context.

Course structure1. The School of Medicine, Dentistry and Biomedical Sciences is dedicated to providing its postgraduate research students with a supportive environment to effectively promote their education, training and professional development. First year students enrol on a tailored training programme comprising a series of lectures, workshops and practical sessions focused on key research skills, including bioimaging, informatics, genomics, mass spectrometry, animal models and clinical trials. In addition, all students receive wide-ranging and ongoing training in generic and transferable skills, such as scientific writing, data analysis, presentation and critical appraisal, through dedicated communication courses and seminars. They also benefit from presentation of their research findings at major national and international conferences, which is an expectation of all postgraduate research students, and through regular interaction with the QUB Graduate School, whose specific function is to support postgraduate training, development and careers.
Students undertake their specific research project under the close guidance of an experienced principal supervisor with support from 1 or 2 co-supervisors as appropriate. All postgraduate research students are initially registered as ‘undifferentiated’ which means that they are required to complete a probationary period after which they are assessed for their suitability to undertake a postgraduate research degree during the differentiation process. Differentiation normally takes place at 9-12 months for full time students and 18-24 months for part time students. Each student is required to complete a literature review, give an oral presentation of their research within their Centre, and provide evidence of appropriate training and completion of their Postgraduate Development Plan. They are then interviewed by a differentiation panel, comprising 2 or 3 academic staff, who assess the students understanding of their project and progress, based on both their submitted paperwork and response to questions. Differentiated students are required to complete a similar Annual Progress Review process in each subsequent year of their research degree. The duration of a full-time PhD programme is normally 3-4 years. For completion of their doctoral qualification students are required to submit a thesis of their research of appropriate length and content (as advised by their supervisors) which will be assessed by oral examination conducted by an external and internal examiner.
Funded postgraduate research studentships are advertised on the School of Medicine, Dentistry and Biomedical Sciences website: https://www.qub.ac.uk/schools/mdbs/Study/PostgraduateResearch/CurrentOpportunities/ . We will also consider applications from externally or self-funded students who should identify potential academic supervisors aligned with their research interests: https://www.qub.ac.uk/schools/mdbs/Research/find-a-phd-supervisor/ Please note that we can only support projects which fit within the overall research strategy of the School and individual research focus of our academic staff.
Students who meet the eligibility criteria for postgraduate research should select ONE potential supervisor from our list of academic staff, https://www.qub.ac.uk/schools/mdbs/Research/find-a-phd-supervisor/, and send an email containing: (1) a brief CV (1-2 pages maximum), (2) a concise statement of motivation including research interests, (3) source of funding, and (4) intended start date.
Our academic staff welcome approaches from prospective students and are happy to develop research proposals of mutual interest. Often this process will involve an informal face-to-face meeting (in person or via teleconferencing) prior to an invitation to submit a formal application. If you have difficulty identifying or contacting an appropriate supervisor, please contact Professor AJ McKnight, Director of Postgraduate Research, firstname.lastname@example.org, or the School Postgraduate Office, email@example.com, who will be happy to help.
Postgraduate students in the School of Medicine, Dentistry and Biomedical Sciences will receive ongoing training in scientific writing, presentation and critical analysis as the basis for a research career. The School supports and challenges its postgraduate research students through robust annual progress review, requiring satisfactory assessment of written work, symposia presentations, supervisor reports and panel interview, the success of which is evidenced by its excellent completion rates. At the end of their postgraduate research training period, students are required to submit a thesis of their research of appropriate length and content which is assessed by oral examination conducted by an external and internal examiner.
Postgraduate research students in the School of Medicine, Dentistry and Biomedical Sciences receive feedback on their written and oral work throughout the period of registration for their degree. This may be both formal and informal and is provided regularly by their supervisors, peers, academic/postdoctoral colleagues, and annual progress review panel.
