Heart disease is one of the main causes of death in the UK and worldwide. At present no widely available, restorative option exists therefore new strategies are required to identify a safe and efficient way of treating heart failure.
In recent years, stem cells have emerged as a potentially valuable tool for the repair of damaged hearts. In particular a breakthrough discovery, which identified that stem cells could be generated from a patient's own skin cells, termed induced pluripotent stem cells (iPSCs). iPSCs have gained increasing recognition given their ability to generate new, patient-specific, cardiac muscle cells, which when delivered into damaged hearts improve cardiac function.
The focus of Dr Lewis-McDougall's research aims to understand the influence of donor age/disease on iPSC potential, identify the optimal iPSC progeny for cardiac repair and investigate extracellular vesicles as mediators of cardiac repair.
I completed a PhD in Stem Cells and Regenerative Medicine from the University of Southampton,
My current research aims to investigate the therapeutic potential of human induced pluripotent stem cell-derived cardiac progenitor cells (hiPSCs-CPCs) and to directly compare with endogenous cardiac progenitor cells (eCPCs) from the same patients.

My research aims to understand the role of atypical chemokine receptors in the alteration of the immune system and subsequent impacts on tumour growth and progression.
My PhD is focused on investigating the expression and function of ACKR4 in the heart. My work aims to characterise localisation and cell type expression of ACKR4, as well as its effect on heart function and health.

Induced pluripotent stem cells regenerative potential in cardiovascular disease
Funded by Barts Charity
IPSCs have been successfully generated from different aged donors however evidence suggests that aged cells generate iPSCs at lower efficiency and may have deteriorated functions making them unsuitable for clinical application. Aging is determined not only by chronological age but also by health condition therefore rigorous testing of iPSCs derived from aged, cardiovascular disease patients is required to provide a clear indication on their suitability for clinical application. This project seeks to identify key ageing molecular signatures and uncover their association with cellular reprogramming in order to select optimal iPSCs for cardiac regenerative therapies.
Therapeutic potential of human induced pluripotent stem cell-derived cardiac progenitor cells: Direct comparison with endogenous cardiac progenitor cells from the same patients
Funded by The British Heart Foundation
The optimal iPSC progeny for cardiac repair is currently unknown and to date the majority of iPSC studies for cardiac repair have focused on generating fully differentiated iPSC-cardiomyocytes. While this approach has shown some promise, a major drawback is that only a single replacement cell type is delivered to the heart. Furthermore, iPSC-cardiomyocytes display an immature phenotype and their integration with the host myocardium often leads to arrhythmias.
As endogenous cardiac progenitor cells (eCPCs) have been widely reported to possess reparative characteristics the generation of human iPSC-CPCs offers an alternative source of renewable precursors where isolation of resident CPCs is not feasible. Given that there is currently much discussion regarding the cardiac regenerative capacity of c-kit+ eCPCs, which is largely based on observations using rodent models, in this project we will directly compare human c-kit+ eCPCs and iPSC-CPCs isolated from the same patients to provide vital information and address the therapeutic potential of this population.
