blastomere

Examples of blastomere in the following topics:

• Cleavage of the Zygote

  • The different cells derived from cleavage up to the blastula stage, are called blastomeres.
  • From here, the spatial arrangement of blastomeres can follow various patterns, due to different planes of cleavage in various organisms.The end of cleavage is known as the midblastula transition and coincides with the onset of zygotic transcription.

• Blastocyst Formation

  • As cell division continues in the morula, the blastomeres change their shape and tightly align themselves against each other.

• Cleavage, the Blastula Stage, and Gastrulation

  • Each cell within the blastula is called a blastomere.

• Cellular Differentiation

  • A pathway that is guided by the cell adhesion molecules is created as the cellular blastomere differentiates from the single-layered blastula to the three primary layers of germ cells in mammals, namely the ectoderm, mesoderm and endoderm (listed from most distal, or exterior, to the most proximal, or interior).
