Modeling and live imaging of mechanical instabilities in the zebrafish aorta during hematopoiesis
Scientific Reports, 2021 All blood cells originate from hematopoietic stem/progenitor cells (HSPCs). HSPCs are formed from endothelial cells (ECs) of the dorsal aorta (DA), via endothelial-to-hematopoietic transition (EHT).
