Confocal immunofluorescence maximal projection of a wild type mouse embryo at embryonic day 3.5, cultured 12 h ex-vivo. CDX2 (green) is a marker of trophectoderm cells which are all outer cells of the blastocyst and will give rise to the placenta. NANOG (purple) marks the pluripotent epiblast cells which will give rise to the mouse embryo. E-cadherin (red) stains cell-cell boundaries. DAPI (blue) stains all nuclei. Image taken by A.
