Individual confocal images for OCT4, KLF2, KLF4, and DAPI are shown with the corresponding composite image. Scale bar 40 μm. () Electro-mobility gel shift assay showing changes in DNA binding activities at a conserved CACC box site in the p18-INK4c gene promoter. Nuclear extracts were generated from ES cells or EBs differentiated for four days in serum. Super-shifts were performed with specific antisera for SP1, SP3, KLF2, KLF3, and KLF4 (See Methods). There is strong binding of endogenous Sp1 to the CACC element in ES cells and EB cells. KLF2 DNA-binding activity is present in ES cells as determined by a specific inhibition of binding of the indicated DNA complex with a KLF2 antibody. This activity is lost upon differentiation into EBs. The identity of the CACC box binding activity in EBs denoted CAC-X, and the binding activity in ES cells denoted CAC-Y, was not definitively identified using this panel of antibodies

In sets 1–7, expression is higher in serum (black sets). In sets 8–9, expression is greater in serum-freeEB culture (red sets). Some sets have been named based on the similarity of overall gene function during differentiation pathways (see Table 3)
