A thin-walled hollow structure in early embryonic development that contains a cluster of cells called the inner cell mass from which the embryo arises. 2, record 1, English, - blastocyst
Record number: 1, Textual support number: 1 CONT
Mammalian development may involve compartments. The fertilized egg divides to form a small ball of cells, the morula ... At the blastocyst stage (3 1/2 days) the proliferating cells have formed two polyclones: the inner cell mass and the trophoblast. 3, record 1, English, - blastocyst

This term is also used to designate the stage characterized by the structure called "blastocyst." 2, record 1, English, - blastocyst

Structure embryonnaire caractérisée par une masse formée de plusieurs feuillets, creusée d'une cavité remplie de liquide (le blastocèle) et qui présente à l'une de ses extrémités un amas de cellules appelé «embryoblaste» ou «bouton embryonnaire». 2, record 1, French, - blastocyste
Record number: 1, Textual support number: 1 CONT
Le développement des mammifères pourrait aussi se dérouler par compartiments. L'œuf fécondé se divise pour former un petit amas de cellules, la morula [...] Au stade du blastocyste (trois jours et demi), les cellules, en se multipliant, ont formé deux polyclones : l'amas cellulaire interne et le trophoblaste. 3, record 1, French, - blastocyste
Record number: 1, Textual support number: 1 OBS
Certains auteurs ne font aucune distinction entre les termes «blastocyste» et «blastula». Toutefois, il s'agit de deux stades différents du développement de l'embryon. En effet, la blastula (comporte un seul feuillet) précède le blastocyste (comporte plusieurs feuillets). 2, record 1, French, - blastocyste
Record number: 1, Textual support number: 2 OBS
Ce terme définit également le stade embryonnaire au cours duquel on trouve cette structure. Il est caractérisé par la disparition de la zone pellucide, qui permet l'implantation de l'embryon dans l'utérus. 2, record 1, French, - blastocyste

Blastocisto : Huevo aproximadamente del cuarto día después de la fertilización. Se desarrolla a partir de la mórula. Está formado por el embrioblasto, estructura celular que da origen al embrión; la cavidad blastocística, que formará la amniótica, y el trofoblasto, estructura celular que da origen a la placenta y sus membranas ovulares. 1, record 1, Spanish, - blastocisto

Au quatrième jour après la fécondation, il se forme, au sein de la masse cellulaire, une cavité. L'œuf est alors appelé «blastocyste». Les cellules se différencient en une couche externe, le trophoblaste (qui deviendra le placenta et ses annexes), et une masse cellulaire interne, l'embryoblaste (ou bouton embryonnaire) à partir de laquelle l'embryon se développera. À ce stade, la membrane pellucide disparaît. 1, record 2, French, - embryoblaste

Al aumentar la cantidad de líquido en la cavidad del blastocisto, las células se separan en dos partes, que comprenden(1) una capa celular externa aplanada(más) trofoblasto, la cual da lugar a la parte embriónica de la placenta; y(2) a un grupo de células localizadas en posición central que se denominan masa celular interna o embrioblasto que es el primordio del embrión. 1, record 2, Spanish, - embrioblasto
