Experimental details: Figure 4 CBP/beta-catenin promotes the maintenance of stem cell reprogramming by Piwil2. (A) GSEA plot showing significant enrichment of the Wnt/beta-catenin signaling activation modules in HaCaT-Piwil2 cells.

(C) Nuclear lysates from HaCaT-Piwil2 cells treated with 20 uM ICG-001, 20 uM IQ-1, or DMSO were coimmunoprecipitated with antisera to beta-catenin and immunoblotted for CBP and p300. (D and E) The expression of Piwil2 and the ""reprogramming"" factors c-Myc, Nanog, Oct4, Sox2 , and Klf4 was determined by real-time PCR and immunoblotting in HaCaT-Piwil2 cells treated with 20 uM ICG-001, 20 uM IQ-1, or DMSO for 24 h. (F) The proportion of CD49f-, CD338-, OCT4-, and ALDHA1-positive cells, determined by flow cytometry in HaCaT-Piwil2 cells treated with 20 uM ICG-001, 20 uM IQ-1, or DMSO for 24 h.

Experimental details: Figure 1. Different Stages during Pancreatic Differentiation Are Associated with Distinct TF Motifs (A) Pancreatic differentiation efficiency was verified by examining lineage markers using flow cytometry. ES, embryonic stem cells; DE, definitive endoderm; FG, posterior foregut; PP1, primary pancreatic progenitor; d, day(s). See STAR Methods for a detailed differentiation protocol. (B) Principal-component analysis (PCA) of ATAC sequencing (ATAC-seq) for the top 3,000 variable peaks. (C) TF motif enrichment during stage transitions. The numbers of opened and closed peaks during stage transitions are indicated. Opened or closed peaks between successive stages were compared with the total atlas to examine the TF motif enrichments using the one-sided Kolmogorov-Smirnov (KS) test. The KS test effect size is shown on the y axis, and the proportion of peaks associated with the TF motif is plotted on the x axis. The size of each circle represents the odds ratio (OR), which was defined as the frequency of the TF in an opened or closed group divided by its frequency in the entire atlas. TF motifs with a KS test effect size >= 0.05 (indicated by the dashed lines) and OR >= 1.2 are shown; when there were more than 10 such motifs, only the top 10 are shown. TF motifs derived from species other than Homo sapiens are marked with brackets. GATA motifs (GATA2, GATA3, GATA4, and GATA6) are marked in red, the HNF1B motif is in blue, and FOXA motifs (FOXA1, FOXA2, and FOXA3) are in green. See al
