Haematopoietic stem cells (HSCs) are first detected in the floor of the embryonic dorsal aorta (DA) and here we investigate the signals that induce the HSC programme there. We show that while continued Hedgehog (Hh) signalling from the overlying midline structures maintains the arterial programme characteristic of the DA roof, a ventral Bmp4 signal induces the blood stem cell programme in the DA floor. This patterning of the DA by Hh and Bmp is the mirror image of that in the neural tube, with Hh favouring dorsal rather than ventral cell types, and Bmp favouring ventral rather than dorsal. With the majority of current data supporting a model whereby HSCs derive from arterial endothelium, our data identifies the signal driving this conversion. These findings are important for the production of HSCs from embryonic stem cells and establish a paradigm for the development of adult stem cells.
