Genetically encoded cortical depletion Emx1-cre (JAX, B6.129S2-Emx1tm1(cre)Krj/J), Esco2fl/fl (JAX, B6N.129S-Esco2tm1.1Ge/J) and C57BL SCID (JAX, B6.Cg-Prkdcscid/SzJ) mice were used to generate the breeding scheme: male Esco2fl/flPrkdcscid/scid × female Emx1-cre+/−Esco2fl/+Prkdcscid/scid. Breeder and offspring cages were supplemented with breeder chow (Envigo Teklad 2919) and DietGel 76A (with plant protein) to help to increase pup survival. Some breeders were more prone to
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
