Figure 5. Development of the cephalic plexus between the 5 and 20 somite embryo.

(A) The vasculature in the 5 somite mouse embryo is a series of disconnected clusters of PECAM-1-expressing cells. The DA and the heart are surface rendered red, PECAM-1 expression throughout the cephalic mesenchyme is surface rendered orange, and the autofluorescence of the mouse embryo is volume rendered with a hot metal colourmap.

(B) By 11 somites, the cells have aggregated into a rudimentary vascular plexus. Larger vessels such as the PHV (blue arrowhead), the PMA (yellow arrowhead) and the ICA (green arrowhead) are visible (see also Supplemental Video S1). The PHV at this stage is a single large vessel that runs in an anterior-posterior direction starting from the cephalic flexure down to the first intersegmental vessel.

(C) The cephalic plexus has remodelled into a more stereotypic pattern by 15 somites. The cephalic veins are easily distinguishable (green bracket).

(D) At 19 somites the cephalic plexus has become more refined into recognizable structures. The cephalic veins are still visible at this stage (green bracket). All scale bars represent 100 microns.
