What's the difference between blastocoele and cavity?
Blastocoele
Definition:
(n.) The cavity of the blastosphere, or segmentation cavity.
Example Sentences:
(1) Invaginating mesodermal cells of the lateral and ventral parts also form pseudopodia, and are in contact with the blastocoelic wall.
(2) The basal lamina could be distinguished from the blastocoelic ECM as a thin coat on the plasma membrane of epithelial cells; the ECM was in contact with this coat.
(3) The cytotrophoblast was restricted to the blastocoel, whilst syncytiotrophoblast intruded to the endometrial basal lamina.
(4) Treatment with retinoic acid, a known regulator of laminin gene expression, not only increased the gene expression of laminin but stimulated the blastocoel expansion without a significant increase in intracellular cAMP levels.
(5) The leading cells form lamellipodia on the roof of the blastocoel and trailing cells form lamellipodia on one another.
(6) When the roof of the blastocoel is inverted the original outer surface, now projecting toward the blastocoel, does not become coated with F-ECM and does not support mesodermal cell migration.
(7) In xenoplastic transplantations, we found that the extracellular matrix on the inner surface of the ESC blastocoel roof serves as a substratum for PIP cell migration.
(8) During preimplantation development of the mouse, embryos pass through a series of morphogenetic events: compaction, fluid accumulation to form the blastocoele (cavitation), and escape from the zona pellucida (hatching).
(9) These data indicate that information present in the host embryo and established well before the mesenchyme blastula stage guides the donor PMCs to the vegetal region of the blastocoel.
(10) The movement of the dorsal mesoderm across the blastocoel roof of the Xenopus gastrula is examined.
(11) The direction of mesoderm cell migration is determined by guidance cues in the extracellular matrix of the blastocoel roof and by an intrinsic tissue polarity of the mesoderm.
(12) At blastula stage 8, cells forming the blastocoelic roof were cultured in isolation as explants.
(13) When migrating mesodermal cells from early gastrulae are cultured on substrata conditioned by deposition of the fibrillar matrix, these cells exhibit striking contact inhibition of locomotion, a phenomenon that may explain dispersal of migrating mesodermal cells across the blastocoel roof.
(14) Lining the blastocoel are patches of endodermal cells in which the actin is exclusively cortical.
(15) After thawing and a one-step dilution of glycerol, embryos were cultured for 48 hr and viability was determined by blastocoel formation.
(16) Antibodies recognizing the external domain of the molecule can, unlike peptides containing the RGD site, block gastrulation when introduced into the blastocoel.
(17) These results constitute the first report of a possible physiological function for cAMP in preimplantation development, namely, in blastocoel formation.
(18) Collectively, all of these treatments indicate that there is a functional association between an asymmetric distribution of organelles along the apical-basal axis of nascent trophectoderm cells and the ability of the embryo to produce nascent blastocoele fluid efficiently.
(19) The four-fold rise in Na,K-ATPase activity during blastocoele formation is not mediated by an increased cellular pool of alpha-subunits.
(20) However, the influence of division order was diminished by a requirement for intercellular cooperation during blastocoel formation and by a counteracting influence of division order arising from its effects on the allocation of cells to the inner cell mass.
Cavity
Definition:
(n.) Hollowness.
(n.) A hollow place; a hollow; as, the abdominal cavity.
Example Sentences:
(1) The content of the cavities was not stained by any of the immunocytochemical reactions applied.
(2) Membranes of this material were filled with islets of Langerhans and implanted in the peritoneal cavity of rats.
(3) In three of these patients this was associated with the presence of a previously well established abscess cavity.
(4) Our experience indicates that lateral rhinotomy is a safe, repeatable and cosmetically sound procedure that provides and excellent surgical approach to the nasal cavity and sinuses.
(5) All patients with localized subaortic hypertrophy had left ventricular hypertrophy (left ventricular mass or posterior wall thickness greater than 2 SD from normal) with a normal size cavity due to aortic valve disease (2 patients were also hypertensive).
(6) In the 12 prognostically most favourable ears the cavity was repneumatized.
(7) Scintigraphic pictures of the uterine cavity and oviducts were obtained with a Jumbo Toshiba gamma-camera; they were subsequently analysed by an Informatek SIMIS-3 data processing system.
(8) The cercaria, microcercous in type, is liberated and actively penetrates a second terrestrial pulmonate where development to the free metacercarial stage takes place in the pericardial cavity.
(9) A new technique to obliterate the mastoid volume or to reduce an old cavity by means of hydroxyapatite granulate is presented.
(10) In general, air from the mediastinum far more often enters the left pleural cavity than the right one.
(11) The advantages of the incision through the pars plana ciliaris are (1) easier approach to the vitreous cavity, (2) preservation of the crystalline lens and an intact iris, and (3) circumvention of the corneal and chamber angle complications sometimes associated with the transcorneal approach.
(12) The rational surgical methods of treatment in 85 patients with suppurative hepatic echinococcosis penetrating into the abdomen cavity are presented.
(13) Finally, carcinoma of the oral cavity in India can be said to be at least two diseases.
(14) A pilot study was undertaken to determine the prevalence of gas in the puerperal endometrial cavity and to determine whether this finding has any relationship to the mode of delivery or to the development of puerperal endometritis.
(15) The authors present a quite unused technique that helps to simplify the cavity preparation in Operative Dentistry.
(16) In several eyes, apparent intraretinal blood-filled cavities were seen acutely in the macular region and elsewhere.
(17) These views are very practical for inferior synovial cavity arthrograms performed in the dental operatory since panoramic radiographic machines have become common in modern dental practices.
(18) Aspergillomas generally arise from saprophytic colonization of a pre-existing pulmonary cavity with Aspergillus, and may be complicated by life-threatening hemoptosis.
(19) Failues of PAFD occurred primarily with the presence of phlegmonous collections and cavities with fistulous connection to bowel.
(20) n. from the body cavity of Scomber scombrus from the Indian ocean is described.
