Haematopoietic stem cells (HSCs) derive from haemogenic endothelial cells of the primitive dorsal aorta (DA) during vertebrate embryogenesis. The molecular mechanisms governing this unique endothelial to haematopoietic transition remain unclear. Here, we demonstrate a novel requirement for fibroblast growth factor

Enterovirus 71 (EV71) infections can cause hand, foot, and mouth disease with severe neurological complications. Because no clinical drug is available for treating EV71 infections, developing an efficient antiviral medication against EV71 infection is crucial. This study indicated that 6-bromo-2-[1-(2,5-dimethylphenyl)-5-methyl-1H-pyrazol-4-yl]
