  • Thus, the genome was not diminished, but rather reproduced during cell division. (Roux's half-embryos were later interpreted to result from the inhibitory effect of the dead blastomere.)
  • blastomere separation
  • a blastomere
  • human blastomeres

Examples

  • Blastomere separation of embryos beyond the 2- to 16-cell stage (depending on species) was noninformative for testing genomic potential because the cells had too little cytoplasm.

    Academic text (1999)
  • Each blastomere can differentiate into various cell types during early development.

  • A blastomere is a cell formed during the early stages of an embryo's development.

  • Researchers study how each blastomere can contribute to the formation of different tissues.

Morphology

blastomere = blasto + mere

A technical formation from Greek combining forms (blasto- + -mere) used in biology; the elements are not productive standalone English words and the meaning is not derivable by a typical B1 learner.

Etymology

The word blastomere comes from Greek parts blasto- meaning 'sprout' or 'bud' and -mere meaning 'part'. So a blastomere is a 'sprout-part', a tiny cell made when a fertilized egg splits, which is why it is one of the first cells in the early embryo.
