Early stage mouse embryos
Early stage mouse embryos at the blastomere stage are visualized in this photo. When embryos were presented as two blastomeres, researchers introduced two different color fluorescent proteins inside each one and, according to the color of the daughter blastomeres, it is possible to see from which maternal cell they did originate.
