Additional file 4: Figure S2. Histone marks at Hmga2 peaks in wt and Hmga2 KD EpiSCs. Chromatin from EpiSCs transfected with control (WT) and Hmga2 targeting siRNAs (KD) was immunoprecipitated with IgG or anti-H3K4me1 or anti-H3K27ac antibodies. Immunoprecipitated DNA was amplified by using oligo pairs annealing to the indicated Hmga2 peaks, which were associated by ChIP-seq with H3K4me1 and/or H3K27ac peaks. A region overlapping the miR-23a gene enhancer was used as a control; Hmga2 peak 10319, not associated with histone modifications, was used as a negative control.
