Two-Cell Embryos Contemplating Cell Fate (IMAGE)
Caption
Bioengineers at UC San Diego have determined through single-cell-RNA-sequencing that embryonic mouse cells show differences in gene expression as early as the two-cell stage of development. In this illustration evoking the 'opposite but interconvertible halves of Yin and Yang,' a two-cell embryo is showing signs of differentiating into a fetus and placenta, the first major task for an embryo.
