In developmental biology cleavage is the division of cells in the early embryo. The process follows fertilization with the transfer being triggered by the activation of a cyclin-dependent kinase complex. The zygotes of many species undergo rapid cell cycles with no significant overall growth producing a cluster of cells the same size as the original zygote. The different cells derived from cleavage are called blastomeres and form a compact mass called the morula. Cleavage ends with the formation of the blast…
Animal cell cleavage furrow formation is caused by a ring of actin microfilaments called the contractile ring which forms during early anaphase. Myosin is present in the region of the contractile ring as concentrated microfilaments and actin filaments are …
Cleavage itself is the first stage in blastulation the process of forming the blastocyst. Cells differentiate into an outer layer of cells (collectively called the trophoblast) and an inner cell mass. With further compaction the individual outer blastomeres the …
After the 7th cleavage has produced 128 cells the morula becomes a blastula. The blastula is usually a spherical layer of cells (the blastoderm) surrounding a fluid-filled or yolk-filled cavity (the blastocoel or blastocyst).. Mammals at this stage form a structure called the blastocyst characterized by an inner cell mass that is distinct from the surrounding blastula.
In biology a blastomere is…
