The cells lying between the primitive endoderm and the polar trophectoderm comprise the embryonic ectoderm or epiblast. |
|
Why then, asks Balfour, are hypoblast and epiblast continuous? |
|
This cell group often splits into an upper layer, the epiblast, and a lower layer, the hypoblast. |
|
These layers do not represent ectoderm and endoderm, respectively, since almost all the cells that form the embryo are contained in the epiblast. |
|
Using Lankester's terms epiblast, hypoblast and mesoblast for the embryonic germ layers, Balfour described chick ectoderm and endoderm for the first time in English. |
|
We also show that 3iL hESCs have a distinct epigenetic landscape, characterized by derepression of preimplantation epiblast genes. |
|
The cells of the primitive embryoblast differentiate into two layers, the epiblast and the hypoblast. |
|
In reptiles, egg-laying mammals, and some birds, a pocket-like depression occurs in the epiblast but encompasses only chordamesoderm or even only the notochord. |
|
Primitive neural stem cells from the mammalian epiblast differentiate to definitive neural stem cells under the control of Notch signaling. |
|
Gastrulation begins dorsally with involution of deep blastoderm cells to form an outer epiblast and inner hypoblast. |
|
This locus drives the expression of Cre throughout the epiblast following implantation. |
|
The homeoprotein Nanog is required for maintenance of pluripotency in mouse epiblast and ES cells. |
|
Scx has an established role in later stages of epiblast maturation: from around E6.5 the epiblast of Scx mutants fails to develop further and does not properly epithelialize. |
|
Unique in its origin, the PICM-19 fetal liver cell line has been isolated from the primary culture and spontaneous differentiation of pig epiblast cells. |
|
In the early embryonic epiblast, some cells develop into the neural system and thus become neural ectoderm, including the neural tube and neural crest. |
