Exempel på hur man kan använda BLASTOCOEL i en mening

• At this stage in mammals the blastula is called the blastocyst, which consists of an outer epithelium, the trophectoderm, enveloping the inner cell mass and the blastocoel.
• As primary mesenchyme cells detach from the vegetal pole in the gastrula and enter the fluid-filled cavity in the center (the blastocoel), the remaining cells at the vegetal pole flatten to form a vegetal plate.
• The epiblast is adjacent to the trophoblast and made of columnar epithelial cells; the hypoblast is closest to the blastocoel (blastocystic cavity) and made of cuboidal cells.
• The Heuser's membrane cells (hypoblast cells) that migrated along the inner cytotrophoblast lining of the blastocoel, secrete an extracellular matrix along the way.
• However, embryos composed of hundreds to more than ~1000 cells still show no evidence of blastocoel formation or the organization of blastomeres into epithelia – epithelialization should be underway in modern embryos with >100 cells.
• They are a "precociously invaginating lineage", meaning that they move into the blastocoel just prior to gastrulation; these four cells then eventually give rise to the larval skeleton.
• In the context of the embryo, active vegetal rotation, together with epiboly of the animal cap ectodermal cells, appears to bring the vegetal mesendoderm into contact with the blastocoel roof.
• At this point, the filopodia appear to move randomly along the surface of the inner blastocoel, making and breaking filopodial connections to the blastocoel wall.
• Blastulation is marked by the appearance of a fluid-filled cavity (blastocoel) surrounded by a single layer of cells called the trophectoderm and the inner cell mass.
• The dorsal lip is formed during early gastrulation as folding of tissue along the involuting marginal zone of the blastocoel forms an opening known as the blastopore.
