Embryonic Capillary Plexus

Embryonic capillary plexus are small blood vessels which form following aggregation of blood islands, their rapid sprouting, acquisition of a lumen, and unification. The plexus gradually take on a horseshoe shape. This plexus is formed within the first three weeks of gestation in humans.

The establishment of endothelial cells in mammals occurs via both extraembryonic and intraembryonic vasculogenesis.
