Vascular Morphogenesis

The vascular tree enables appropriate blood distribution and supply to all tissues in several multicellular organisms. The vascular network is essential for embryonic development, growth and wound healing. Importantly, many human disorders arise from mis-patterning of blood vessels, such as in diabetic retinopathy, ischemia, stroke, or tumour angiogenesis.

The formation of a functional vascular network requires simultaneous peripheral sprouting of newly formed blood vessels into avascular tissues and remodelling of the primitive amorphous vascular plexus into a hierarchical network of arteries, capillaries and veins. These two processes are tightly regulated by molecular communication between cells in the tissue and endothelial cells (the cells lining the blood vessels). Notably, it is now becoming evident that endothelial cells need to coordinate their individual behaviours to enable coherent and functional vascular network formation.

The Vascular Morphogenesis Lab has the aim to understand the molecular mechanisms regulating coordinated endothelial cell behaviour during sprouting and remodelling phases of the angiogenic process.
