Before anything else, a stem cell must first put the brakes on its “stem-cell” program

Developing bone in normal (top) and mutant (bottom) embryos. Protrusions in a developing bone are formed by a distinct class of cells (green) that differ from the regular bone-forming cells (yellow-orange). Incorrect regulation and distribution of these cells leads to irregularities in the shape of the forming bone

How does the fertilized egg start the process of becoming a diversified organism?

Embryonic stem cells (marked in green fluorescent protein) that should become sex cells, in which the gene encoding Utx is not present. Each column shows a gene needed for sex cell development (top row – marked in red, purple and orange). After 12 days (bottom row) the expression of the four genes has stopped and, rather than develop into sperm or ova, the stem cells die
