Biography
Sanjay Sinha is a British Heart Foundation (BHF) Senior Research Fellow and a Professor in Cardiovascular Regenerative Medicine at the University of Cambridge. He completed medical training in Cambridge, followed by cardiology clinical training and a PhD in Manchester. Dr Sinha then carried out post-doctoral studies in the USA with Prof Gary Owens on smooth muscle biology before establishing an independent group at Cambridge. He is also a Consultant in Cardiology and he combines his research work with clinical duties at Addenbrooke’s Hospital, Cambridge, where he treats patients with a wide variety of cardiovascular diseases.

Research
The Sinha lab’s overall aim is to develop new treatments for cardiovascular diseases, using their expertise in cardiovascular development, regeneration and disease modelling.
They have pioneered the generation of embryonic lineage-specific vascular smooth muscle cells from human embryonic stem cells (hESC) and induced pluripotent stem cells, using chemically defined conditions. They have utilised this system to model genetically triggered aortopathies, such as Marfan and Loeys-Dietz syndromes. These “disease-in-a-dish” models are being used to understand the pathobiology of these conditions and to screen for new treatments.
Additionally, they are they are generating a detailed multiomic and spatial atlas of human heart development and modelling key developmental niches and events in vitro using hESC-based 3D system to define key regulatory mechanisms in humans.
Finally, they are testing the regenerative potential of hESC-derived epicardium and other cardiovascular cell types for heart repair after myocardial infarction, either through direct injection or in the form of an in vitro generated myocardial “patch”.

Plain English
Blood vessel diseases cause heart attacks, strokes and aortic aneurysms (a ballooning then tearing of the main artery in the body). We use human stem cells to generate smooth muscle cells, one of the main cell types that make up the blood vessel wall. If we use skin cells from patients with vascular diseases to make stem cells then the smooth muscle cells from those (induced) stem cells will have the same abnormalities as in the patient, thus providing a way to generate a "disease-in-a-dish". With these and other approaches we are trying to understand how blood vessels become diseased and trying to find new treatments for these diseases. We are also developing ways to transplant our stem cell generated cells to reverse the damage caused by a heart attack.
