When a fertilized mammalian egg divides, it yields two seemingly identical daughter cells. Some of their descendants generate the diverse organ systems of the embryo, while others form extra-embryonic tissues that sustain the developmental process. In 2025, researchers used a cutting-edge technique known as single-cell proteomics (SCP) to show that even in the two first-generation
