His team discovered how to generate functional hemangioblasts (a population of "ambulance" cells) from human embryonic stem ... "Generation of functional hemangioblasts from human embryonic stem cells". Nature Methods. 4 (6): 501-509. doi:10.1038/nmeth1041 ...
Then, in 1932, Murray detected the same event and created the term "hemangioblast" for what Sabin had seen. It is important ... Further evidence to corroborate hemangioblasts come from the expression of various genes such as CD34 and Tie2 by both lineages ... This observation gave rise to the hypothesis that the two lineages come from the same precursor, termed hemangioblast. Even ... Some researchers have found that cells with hemangioblast properties have been located in the posterior end of the primitive ...

The haemangioblast generates haematopoietic cells through a haemogenic endothelium stage. Nature 2009;457:892-895 v t e (Cell ... The development of hematopoietic cells in the embryo proceeds sequentially from mesoderm through the hemangioblast to the ...
They develop from undifferentiated hemangioblasts in blood vessels in the walls of the umbilical vesicle, allantois and chorion ... Vasculogenesis begins as mesodermal cells differentiate into hemangioblasts, which in turn differentiate into angioblasts. ...
... acts upstream of hemangioblast genes such as scl, fil1, and etsrp. AGGF1 acts similarly to VEGF - another gene implicated ... AGGF1 is critical to the specification of veins and multipotent hemangioblasts, anti-inflammation, tumour angiogenesis, and ... "Aggf1 acts at the top of the genetic regulatory hierarchy in specification of hemangioblasts in zebrafish". Blood. 123 (4): 501 ...
Embryonic vasculogenesis occurs when endothelial cells precursors (hemangioblasts) begin to proliferate and migrate into ...
... s are one of the two products formed from hemangioblasts (the other being multipotential hemopoietic stem cells). ...
Other studies done in zebrafish have more soundly indicated the existence of the hemangioblast. While the hemangioblast theory ... The hemangioblast theory, which posits that the RBCs and ECs derive from a common progenitor cell, was developed as researchers ... However, Ueno and Weissman provided the earliest contradiction to the hemangioblast theory when they saw that distinct ES cells ...
... from mesodermal hemangioblasts. In the centre of a blood island, hemangioblasts form the haematopoietic stem cells that are the ... In the periphery of a blood island the hemangioblasts differentiate into angioblasts, the precursors to the blood vessels. The ...
Hemangioblasts (or their in vitro counterpart, blast-colony forming cells) are cells believed to give rise to both the ... This, and the existence of hemogenic endothelium, led to a belief and search for adult hemangioblast- or angioblast-like cells ...
Structures called blood islands form in the mesoderm layer of the yolk sac by cellular differentiation of hemangioblasts into ...
... which is thought to originate from endothelial cells or hemangioblasts, which are capable of forming both endothelium and ...
In 1997, Keller's team was the first to successfully isolate the developmentally significant hemangioblast-a multipotent ...
Stainier developed and used single-cell analyses to provide the first in vivo demonstration of the hemangioblast, a formerly ...
