Blastomere - Wikipedia
In biology, a blastomere is a type of cell produced by cell division (cleavage) of the zygote after fertilization; blastomeres are an essential part of blastula formation, and blastocyst formation in …
Blastulation - Wikipedia
Blastulation is the stage in early animal embryonic development that produces the blastula. In mammalian development, the blastula develops into the blastocyst with a differentiated inner …
The first two blastomeres contribute unequally to the human …
We discovered that the majority of cells in the EPI, the future human body, originate from one of the two cells in most embryos. Notably, the first blastomere to divide at the 2-cell stage has a …
Blastomere | biology | Britannica
blastomeres resulting from a number of cleavages of a zygote, or fertilized egg. Its name derives from its resemblance to a mulberry (Latin: morum). A morula is usually produced in those …
43.5B: Cleavage, the Blastula Stage, and Gastrulation
2023年10月31日 · During cleavage, the cells divide without an increase in mass; that is, one large single-celled zygote divides into multiple smaller cells. Each cell within the blastula is called a …
An Introduction to Early Developmental Processes
After fertilization, the development of a multicellular organism proceeds by a process called cleavage, a series of mitotic divisions whereby the enormous volume of egg cytoplasm is …
Cleavage (embryo) - Wikipedia
The different cells derived from cleavage are called blastomeres and form a compact mass called the morula. Cleavage ends with the formation of the blastula, or of the blastocyst in mammals.
Embryonic Development, Cell Division & Gastrulation - Britannica
blastula, hollow sphere of cells, or blastomeres, produced during the development of an embryo by repeated cleavage of a fertilized egg. The cells of the blastula form an epithelial (covering) …
Blastomere - an overview | ScienceDirect Topics
Blastomere biopsy is a relatively standardized procedure used in preimplantation genetic diagnosis (PGD) where one or two blastomeres from six- to eight-cell embryos are extracted …
Dynamic blastomere behaviour reflects human embryo ploidy by …
Here we combine non-invasive time-lapse imaging with karyotypic reconstruction of all blastomeres in four-cell human embryos to address the hypothesis that blastomere behaviour …
