What's the difference between hypoblast and hypoblastic?
Hypoblast
Definition:
(n.) The inner or lower layer of the blastoderm; -- called also endoderm, entoderm, and sometimes hypoderm. See Illust. of Blastoderm, Delamination, and Ectoderm.
Example Sentences:
(1) Gastrulation is accompanied by a sharp increase in the AChE activity which was most pronounced in anterior hypoblast.
(2) (1) Removal of both the area opaca and the marginal zone of the area pellucida from a blastoderm stripped of its hypoblast (type-IV operation) prevents the regeneration of a normally functioning primary hypoblast.
(3) These results show that the two main properties of the posterior marginal zone (contributing to the hypoblast and controlling the site of primitive streak formation) are separable, and reside in different germ layers.
(4) The 36 hour stage was represented by bulky growth of mesodermal-like cells and changes in hypoblast layer where some of the cells degenerated and some were transformed to mesenchymal spindle-like cells.
(5) Tritiated quail hypoblast (after incubation of the embryo in the presence of 3H-glucosamine) was transplanted onto unlabelled chicken blastoderm deprived of its hypoblast.
(6) In the area pellucida, the fibronectin was (1) associated with the basal lamina of the epiblast, (2) present between epiblastic and hypoblastic cells and (3) occasionally internalized in hypoblastic cells.
(7) It was found that the deep (endodermal) portion of the posterior marginal zone contributes to the hypoblast and to the junctional endoblast, while the epiblast portion of the same region contributes to the epiblast of the primitive streak and to the definitive (gut) endoderm derived from it.
(8) TGF-beta 1 precursor was seen in both the epiblast and the hypoblast.
(9) Removal of the deep part of the marginal zone prevents regeneration of the hypoblast but not the formation of a primitive streak.
(10) Chick embryos treated with tunicamycin (TN), a specific inhibitor of N-linked glycosylation of proteins, show little or no ECM, diminished cell adhesion and a dramatic alteration in the architecture of the epiblast and of the hypoblast.
(11) A chemical basis for the transmission of signals during gastrulation has been investigated by using chimaeric embryos resulting from the combination of 3H-glucosamine-labelled and unlabelled hypoblast with epiblast taken from chicken and quail embryos at stage 3 of Vakaet (1970).
(12) The roof of the vesicle is constructed to rather large columnar cells which are in continuity wiht hypoblast cells.
(13) By contrast, alpha-amanitin resulted in a decrease in synthesis of several polypeptides, which are either undetectable or weakly present in the hypoblast.
(14) It was found that the first cells that appeared between the primitive endoderm (hypoblast) and trophoblast were separated from the latter by a basal lamina but appeared to be either loosely attached to the endoderm or to have been detached from it.
(15) The hypoblast explant tended to fragment into smaller groups of cells, many of which migrated around the definitive endoblast, thus mimicking the situation in vivo.
(16) Transfer of label may occur to mesoblast cells, but not between chicken and quail hypoblast cells.
(17) The morphology of the chimaeric embryos, as studied by scanning electron microscopy, suggests a direct deposition of these macromolecules by filopodia of the dorsal surface of the hypoblast.
(18) The labeled hypoblast was recombined with its denuded unlabeled epiblast.
(19) In comparison with the definitive endoblast, the hypoblast cells attached more readily to the glass, produced larger ruffle membranes, moved more rapidly, showed poorer contact-inhibition of locomotion and showed a greater tendency to break away from the main explant.
(20) The hypoblast, mesoderm and epiblast of gastrulating chick embryos have some HNK-1-related proteins in common, while others are unique to specific tissues.
Hypoblastic
Definition:
(a.) Relating to, or connected with, the hypoblast; as, the hypoic sac.
