One of the individual cells created when a fertilized egg divides during the early stages of embryonic development.
From Greek 'blasto-' (germ, bud) and 'meros' (part), coined in the 1800s to name the building-block cells of developing embryos.
Each blastomere is like a Lego brick with a genetic instruction manual—in some species, a single isolated blastomere can still develop into a complete organism, proving early embryonic cells are remarkably flexible.
