Dr Margariti has developed significant expertise in stem cell biology, with particular emphasis on cell reprogramming, chromatin remodelling, cell signalling and endothelial cell biology. She had received her postdoctoral training in the Cardiovascular Division of the BHF Centre of Excellence at King’s College London (KCL). In 2013 Dr Margariti was appointed as a Lecturer in the Centre for Experimental Medicine (CEM), in Queen’s University Belfast (QUB). She has received a BBSRC New Investigator award to study the mechanisms of endothelial cell direct reprogramming and a range of BHF grants to study the endothelial cell dysfunction. Dr Margariti and her team have worked extensively to elucidate the underlying mechanism of endothelial cell reprogramming and they have generated functional endothelial cells based on a fully defined environment. In 2017 the team has published that the RNA binding protein QKI is a key player on endothelial cell reprogramming inducing neovascularisation and angiogenesis, while more recently they have shown the mechanism whereby FSTL3 enhances the function of iPS-ECs. In parallel, Dr Margariti’s laboratory has invested on their unique expertise on cell reprogramming and induced pluripotent stem (iPS) cell technologies and they have developed patient- specific cells lines from diabetic donors (patient specific iPS cell lines in a petri dish) based on fast and highly efficient approaches. To date, the group has generated more than 120 diabetic specific iPS cell lines from small volumes of patient blood based on highly novel and robust protocols. These patient-specific cells are now valuable tools to study the underlying causes and mechanisms of the pathogenesis of the endothelial cell dysfunction and develop new knowledge, biomarker of diabetes and vascular complications, and discover effective therapies. Dr Margariti has been promoted to Senior Lecturer in 2017 and she is leading the iPS cells facilities in CEM in QUB, where iPS cells are generated and differentiated towards vascular cells (including ECs, Smooth Muscle Cells and Pericytes) and human blood vessel organoids, Cardiomyocyes, Neurons, Retina pigment epithelial cells and many other cell types. The team is located in the CEM which provides a vibrant and growing research centre focused on vascular biology. The Centre has moved into a purpose-designed £32M Research building (~4,742m2) partly funded by a Wellcome Trust-Wolfson Capital Award. Dr Margariti has published a number of high-quality papers, and the impact of her research has been recognised by several prestigious awards, including the PAPANIKOLAOU Prize from the Hellenic Medical Society for significant contribution to medical research and the prize for outstanding performance and scientific research awarded by the KCL. She has also established collaborations with two of the leading cell reprogramming laboratories in the world. Prof Deepak Srivastava in University of California, San Francisco (UCSF), who is internationally renowned for his studies in cell reprogramming, and Prof George Daley, the Director of the Stem Cell Transplantation Program at Children’s Hospital Boston in Harvard Medical School, whose group are world leaders in the studies in development and cellular reprogramming.

Dr Margariti’s research is demonstrating that the therapeutic potential of “re-born” reprogrammed endothelial cells have transforming consequences for regenerative and personalised medicine.

The road to novel regenerative therapy using direct reprogramming approaches will be challenging and hard, but the journey has already begun...
