Blood develops initially within the core of "blood islands" in the mesoderm. During development, there follows a series of "relocations" of the stem cells to different organs within the embryo. In the adult, these stem cells are located in the bone marrow. At the time when blood first forms, there are no bones!
Angioblasts initially form small cell clusters (blood islands) within the embryonic and extraembryonic mesoderm. These blood islands extend and fuse together making a primordial vascular network. Within these islands the peripheral cells form endothelial cells while the core cells form blood cells (haemocytoblasts).
Recent work has shown that the formation of the initial endothelial tube is by a process of coalescence of cellular vacuoles within the developing endothelial cells, which fuse together without cytoplasmic mixing to form the blood vessel lumen.

Endothelial Tube Formation
The following data is from a recent review.
|Shh||Loss of Shh results in lack of arterial identity in zebrafish. Shh acts upstream of VEGF.|
|VEGF||VEGF acts downstream of Shh signaling to activate Notch via the PLCγ/ERK pathway in zebrafish. Mutant mice expressing only VEGF188 lack arterial differentiation.|
|Nrp1||Null mice display impaired arterial differentiation. Nrp1 is involved in a positive feedback loop of VEGF signaling.|
|Notch||Notch acts downstream of Shh and VEGF signaling in zebrafish. Notch1; Notch4 mutant mice have abnormal vascular development.|
|Dll4||Null mice lack arterial specification.|
|Dll1||Null mice fail to maintain arterial identity.|
|Hey1/2 (Grl)||Null mice lack arterial specification. Lack of grl in zebrafish results in loss of arterial specification.|
|Foxc1/c2||Foxc1; Foxc2 mutant mice lack arterial specification. Foxc1 and Foxc2 directly regulate Dll4 and Hey2 expression. Foxc1 and Foxc2 are also involved in lymphatic vessel development.|
|Sox7/18||Lack of Sox7/18 results in loss of arterial identity in zebrafish.|
|Snrk-1||Snrk-1 acts downstream or parallel to Notch signaling in zebrafish.|
|Dep1||Dep1 acts upstream of PI3K in arterial specification in zebrafish.|
|Crlr||Shh regulates VEGF activity by controlling crlr expression in zebrafish.|
|EphrinB2||Null mice lack boundaries between arteries and veins. EphrinB2 is involved in lymphatic vascular remodeling and maturation.|
|COUP-TFII||COUP-TFII suppresses arterial cell fate by inhibiting Nrp1 and Notch. COUP-TFII also interacts with Prox1 to regulate lymphatic gene expression.|
|EphB4||Null mice lack boundaries between arteries and veins.|
|Sox18||Null mice fail to specify lymphatic endothelial cells. Sox18 induces Prox1 expression.|
|Prox1||Prox1 induces lymphatic markers and maintains lymphatic cell identity.|
Vascular Endothelial Growth Factor
Growing blood vessels follow a gradient generated by tagret tissues/regions of Vascular Endothelial Growth Factor (VEGF) to establish a vascular bed. Recent findings suggest that Notch signaling acts as an inhibitor for this system, preventing sprouting of blood vessels.
Notch is a transmembrane receptor protein involved in regulating cell differentiation in many developing systems.

Regulators of Growth
The following data is from a review article on ovary vascular development.
Stimulators of Angiogenisis
Inhibitors of Angiogenisis
Vein Light Microscopy
The entire developing and adult cardiovascular system (blood vessels and heart) is lined by a simple squamous epithelium. (Stain - Haematoxylin Eosin)
Cardiac Blood Vessels
Earliest vessels in the heart wall develop subepicardially (beneath the outside surface of the heart) near the apex at Carnegie stage 15, which then extends centripetally and at stage 17 coronary arterial stems communicate with the aortic lumen.
Due to the extensive embryonic, and ongoing, remodelling of the vascular system, there are many different vascular variations and anomalies.
