Pluripotent stem cells for vascular differentiation and disease modeling

Home: Overview

RESEARCH

Blood vessels are essential for proper functioning of tissues and organs in our body, and vascular dysfunction is associated with many cardiovascular and neurodegenerative diseases. Insight into the  interactions between vascular cells and the local microenvironment are therefore key to understanding many different diseases.  Human induced pluripotent stem cells (hiPSCs) derived from patients with genetic vascular disorders can form blood vessel cells and provide human models for disease that can be used to find new therapeutics and strategies for disease prevention.

DIFFERENTIATION OF HIPSCS

We utilize hiPSCs derived from healthy donors and patients with genetic vascular disorders. Over recent years, we have developed efficient protocols to differentiate different endothelial cell (EC) subtypes, pericytes, vascular smooth muscle cells, as well as myeloid cells, such as monocytes and macrophages. Specifically we investigate the generation of tissue-specific vascular cells with focus on the heart and brain vasculature.

VESSELS ON A CHIP

We trying to recreate both micro- and macrovascular- structures inside of microfluidic devices. For this we use modling approach to create tubes of around 100-150um in diameter and
self-organisation in microfluidic devices or chips, to create perfused micro-vessels on average 10-50um in diameter. Additionally, we are exploring photopatterning technologyto to recreate the same pattern repeatedly and thus eventually make micron-size self-organised structures of endothelial cell tubes.

DISEASE MODELS

Using these 3D vessels on a chip and hiPSC from patients we aim to develop realistic disease models for hereditary hemorrhagic telangiectasia (HHT) and cerebral amyloid angiopathy (CAA), and model tumour angiogenesis and inflammation with patient-specific hiPSCs.

RNA-SEQ

Using CRISPR/Cas9 based gene targeting, we have generated several fluorescent reporter hiPSC lines for core transcriptional factors (TF) that are being used to advance our understanding of lineage specification and differentiation of ECs with different mesodermal origins and distinguishable by their core transcriptional signature.
