Project description: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 Foxa and Hnf4alpha during conversion event to iHep cells.

Then we used ChIP-seq to explore the targets of Foxa and Hnf4alpha during conversion event to iHep cells. Besides we performed for hepatocytes.
Project description:We have found that 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, and DNA binding, N-terminal, and C-terminal domains (DBD, NTD, and CTD, respectively) of Foxa proteins are swappable in the direct reprogramming of the iHep cells. Then we used ChIP-seq to explore the targets of the domain swapped mutant forms of Foxa proteins during conversion event to iHep cells.

Then we used ChIP-seq to explore the targets of Hnf4alpha during conversion event from MEFs to iHep cells.
Project description:Foxa and Hnf4alpha targets during conversion from mouse embryonic fibroblasts (MEFs) to hepatocyte-like (iHep) cells and hepatocytes (Hep).
Project description: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 RNA-seq to explore the conversion event to the iHep cells.
Project description: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 the transduced Foxa and Hnf4alpha proteins in MEFs.
Project description: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 (iHep cells) in vitro. Then we mapped 2 histone modification marks (H3K9ac and H3K27me3) and 2 states of Pol2 (with phosphorylated serine 5 and phosphorylated both of serine 5 and serine 2) during the conversion event. Besides we performed FAIRE-Seq to explore the chromatin accessbility in the iHep cells.
