Regulation of plasticity in cardiovascular health and disease
Tissue homeostasis and regeneration after injury rely on mobilisation of tissue resident stem and progenitor cells or de-differentiation of functional cell types. Our group investigates the regulation of such cell plasticity in the cardiovascular system and how this is perturbed in disease. Our recent work demonstrates that a small number of cells proliferate extensively to form lesions in vascular disease models.
