Fig. 7

The Sox2 O-GlcNAcylation level is high under ESC self-renewal conditions and decreases upon ESC differentiation. When Sox2 T258 O-GlcNAcylation is inhibited, the suppression of developmental genes by Sox2 does not occur properly, decreasing ESC self-renewal. In addition, Sox2 T258 O-GlcNAcylation is important for the development of ectoderm through the repression of mesendodermal genes. The reduction in Sox2 T258 O-GlcNAcylation during early embryonic development decreases the number of cells committed to an ectodermal lineage.
