Sall4 is required for primordial germ cell (PGC) specification; conditional inactivation of Sall4 during PGC specification leads to apoptosis and failure of PGC translocation from mesoderm to endoderm, with derepression of somatic program genes Hoxa1 and Hoxb1 while stem cell program activation is intact. Sall4 binds these somatic gene loci (ChIP) and likely recruits a histone deacetylase repressor complex with Prdm1. |
