A Binding dynamics of OCT4, SOX2 and ESRRB upon GATA6 induction, both at GATA6 peaks showing pluripotency TF binding before or during differentiation (i.e., GATA6 peaks lacking pluripotency TF binding are omitted) and at other pluripotency TF binding sites in undifferentiated ES cells. B Correlations between categories of GATA6 binding segregated by pluripotency TF binding ( X axis) and by GATA6 dynamics (top; Y axis) or by SOX17 binding (bottom; Y axis). The dependency between variables was assessed with two-sided Chi-square tests ( p < 2.2e-16). C Log2 odds ratio of the proportion of regions displaying ectopic pluripotency TF binding across different GATA6 binding groups shown on the left. The statistical significance of the enrichments/depletions was assessed with two-sided Fisher's Exact tests ( p < 1.3e-155). D Average profiles of GATA6 binding, SOX17 binding, chromatin accessibility (small ATAC-seq fragments) and nucleosome positioning (MNase-seq) at regions displaying no pluripotency TF binding at all (noPTF) or an ectopic recruitment (ectopic), throughout GATA6 induction (colored lines). All plots are centered on the GATA6 summit. E Statistical association of GATA6 binding regions divided by pluripotency TF binding groups, with the six groups of differentially expressed genes shown in Fig. , measured with two-sided Fisher Exact tests at increasing distances. Source data are provided as a Source Data file.

Figure Legend Snippet: A Representative photomicrographs of cells subject to GATA6 induction and to either non-targeting control siRNAs or Oct4 knockdown for 4 days ( n = 6 independent kd). The scale bar represents 100 µm. B Immunostaining of SOX17 and PDGFRa after 4 days of GATA6 induction and control or Oct4 siRNAs (representative of 6 independent kd). The scale bar represents 30 µm. C Average profile of GATA6 and SOX17 binding at regions identified as showing decreased or increased GATA6 binding (FDR < 0.1 and absolute Fold-change > 0.5) after 2 days of GATA6 induction and Oct4 knockdown. D Log2 odds ratio of the proportion of regions displaying decreased or increased GATA6 binding across groups of regions displaying different behaviors of pluripotency TF binding, shown on the bottom. The statistical significance of the enrichments/depletions was assessed with two-sided Fisher Exact tests ( p = 3.8e-174 and 8.5e-107 for regions binding pluripotency TFs from d0 or ectopically, respectively). E Statistical association of GATA6 binding regions showing increased or decreased GATA6 binding upon Oct4 knock-down, with genes displaying down or upregulated expression, measured with Fisher's Exact tests at increasing distances. F Expression of endogenous Gata6 expression, measured by quantification of its 5’UTR absent in the ectopic transgene, upon control or Oct4 knock-down during GATA6 induction (day 2; paired two-sided T test p = 0.003992; n = 6 independent kd; median—bar; 25–75% percentiles—box; 1.5-folds the inter-quartile range—whiskers). G Identification of an active enhancer based on histone marks (top) ~65 kb upstream of Gata6, showing no TF binding before differentiation but rapidly recruiting GATA6 and SOX17 and displaying ectopic OCT4/SOX2 binding during GATA6 induction.

Summary of the molecular observations reported in this study, highlighting different modes of GATA6 binding (opportunistic or pioneer), different dynamics (early versus late and stable versus transient) and different outcomes regarding: recruitment of SOX17 or of OCT4/SOX2; chromatin structure; gene regulatory influences at early, mid or late responsive genes; the occurrence of DNA motifs. A caption and a diagram of the epistatic interactions emerging from kinetic analyses and OCT4-depleted cells are shown.
