Targets of Hnf4alpha during conversion from mouse embryonic fibroblasts (MEFs) to hepatocyte-like (iHep) cells.

We have found three specific combinations of two transcription factors, comprising Hnf4alpha plus Foxa1, Foxa2 or Foxa3, could convert mouse embryonic fibroblasts (MEFs) into cells that closely resemble hepatocytes in vitro. Then we used ChIP-seq to explore the targets of Hnf4alpha during conversion event from MEFs to iHep cells. Overall design: Using an anti-Hnf4alpha antibody we performed ChIP-Seq for iHep_4a1 cells (Foxa1/Hnf4alpha), iHep_4a2 cells (Foxa2/Hnf4alpha), iHep_4a3 cells (Foxa3/Hnf4alpha).
