Blastulation is the stage in early animal embryonic development that produces the blastula. In mammalian development, the blastula develops into the blastocyst...

Development of an organism happens through fertilization, cleavage, blastulation, gastrulation, organogenesis, and metamorphosis into an adult. Each species...

pellucida is referred to as a morula. Cleavage itself is the first stage in blastulation, the process of forming the blastocyst. Cells differentiate into an outer...

blastocyst, containing a differentiated inner cell mass and trophectoderm. blastulation A stage in the embryonic development of all animals defined by the formation...

extraembryonic structures that do not directly contribute to the embryo. After blastulation, the trophoblast is contiguous with the ectoderm of the embryo and is...

the morula. Through the processes of compaction, cell division, and blastulation, the conceptus takes the form of the blastocyst by the fifth day of development...

develops into a structure called a blastula through a process called blastulation. The blastula develops into a structure called a gastrula through a process...

from 1 to 3 cells, as well as the initiation of compaction and start of blastulation. Also, two-pronuclear zygotes (2PN) transitioning through 1PN or 3PN...

embryonic development, paracrine/juxtacrine signaling of hCG induces blastulation and neurulation. An in vitro model of early human embryogenesis (human...

differences in birefringence between eggs, which is a predictor of compaction, blastulation and pregnancy. Potentially, polar body biopsy may be used for molecular...

expression of genes that give rise to the embryonic developmental process of blastulation. The loss of stiffness-controlled transcription factor Cdx leads to the...

of in vitro culture. This allows the developing TE to protrude after blastulation, facilitating the biopsy. On day five post-fertilization, approximately...

trophectoderm. As the trophectoderm separates from the inner cell mass during blastulation, early trophoblasts begin to form the placenta. Later in placental development...

regulating the process of fertilization, as well as early embryo development, blastulation and gastrulation. He was also interested in the origin of the primary...

(2007) The axis of polarity of the mouse blastocyst is specified before blastulation and independently of the zona pellucida. Hum. Reprod. 22, 798–806. Gardner...
