(D-G) Gene Set Enrichment Analysis (GSEA) was performed in sorted stem and progenitor cells from AhR WT (n=3) and KO (n=4) mice (D&E) and in WT mice in response to vehicle and TCDD treatment (F&G). Normalized enrichment scores (NES) and FDRs were calculated using the Public Interaction Database (PID) for the FoxM1 Pathway gene set.
