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 mammals.

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) layer, called the blastoderm, enclosing a fluid-filled cavity, the blastocoel.

The meaning of BLASTOMERE is one of the cells that are produced during cleavage of a zygote and that form the morula.

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 cell mass and an outer trophectoderm.

May 23, 2024 · 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 higher likelihood to generate the …

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 divided into numerous smaller, nucleated cells. These cleavage-stage cells are called blastomeres.

The human begins as the fertilized ovum, which cleaves itself into smaller and smaller embryonic cells known as blastomeres, each carrying all the genetic information needed to build any tissue or organ in the body (Standring et al., 2008).

After fertilization, the human zygote divides by mitoses into several smaller cells called blastomeres. This process of division, known as cleavage, is a period of intense DNA replication and cell division, with no discernible increase in overall cellular size. Cytoplasmic division occurs after nuclear replication.

A blastomere is a cell that results from the division of a fertilized egg during early embryonic development. These cells are produced through a process called cleavage, which occurs after fertilization, leading to the formation of a multicellular embryo.
