Blastomeres are early embryonic cells that make up the blastula stage of development. These cells undergo mitotic division to generate the pluripotent cells necessary for differentiation into specialized cell types. There are several synonyms for blastomeres, including embryonic cells, blastula cells, and pluripotent cells. Other related terms include blastomere lineage and blastomere segregation. Understanding the terminology associated with embryonic development is crucial for researchers and clinicians working in the fields of genetics and regenerative medicine. By using precise language, professionals can communicate effectively about the intricate processes involved in early-stage embryonic development.
