Cells in the Early Embryo Battle Each Other to Death for Becoming Part of the Organism (Science Daily)
Spanish researchers at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have found that during the early stages of mammalian development, embryonic cells embark on a battle for survival. Through this battle, the less active of these cells are eliminated by their stronger sisters. The work is published in the journal Nature.

Center, three days later, the green cells, in which Myc protein increased, have won the battle and removed the blue. Right, This shows more Myc cell (green) engulfing its neighbor. (Credit: CNIC)
