Global gene expression analysis for mouse embryonic fibroblasts (MEFs), induced hepatocyte-like (iHep) cells and adult mouse hepatocytes.

ABSTRACT: In order to characterize iHep cells more precisely, we conducted global gene expression analyses using microarrays to compare among the gene expression profiles of MEFs, iHep cells and adult mouse hepatocytes.

Global gene expression analysis for mouse embryonic fibroblasts (MEFs), induced hepatocyte-like (iHep) cells and adult mouse hepatocytes.

Project description:In order to characterize iHep cells more precisely, we conducted global gene expression analyses using microarrays to compare among the gene expression profiles of MEFs, iHep cells and adult mouse hepatocytes. Three MEF samples that were individually prepared from 13.5 days post coitum (dpc) embryos, three types of iHep cells and hepatocytes obtained from the adult mouse liver were used.

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 ChIP-seq to explore the targets of Foxa and Hnf4alpha during conversion event to iHep cells. Besides we performed for hepatocytes.

Genome-wide maps of the chromatin and transcription state transition during conversion from mouse embryonic fibroblasts (MEFs) to hepatocyte-like cells (iHep)

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.

Transcriptome analysis of the induced hepatocyte-like (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 RNA-seq to explore the conversion event to the iHep cells.

Induction of functional differentiation of induced hepatocyte-like (iHep) cells

Project description:iHep cells maintained in two-dimensional (2D) culture can become functionally close to hepatocytes by forming cell aggregates under three-dimensional (3D) culture condition.

Targets of DNA binding, N-terminal, or C-terminal domain swapped mutant forms fo Foxa proteins in induced hepatocyte-like (iHep) cells.

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.

Generation of integration-free induced hepatocytes from mouse fibroblasts

Project description:Previous studies demonstrated that hepatocyte-specific transcription factors could directly convert fibroblasts into functional hepatocytes-like cells, namely induced hepatocytes (iHeps) using viral systems. However, viral integration into host genome causes insertional mutation and risk of tumorigenecity. we showed iHeps could be generated from MEFs using the integration-free system. They were expandable in vitro and showed hepatic features, similar to primary hepatocytes. iHeps_G4H1F3 transfected (Episomal vectors) and iHeps_G4H1F3 transduced (pMXs) were duplicate, respectively. MEFs and primary hepatocytes were used as negative and positive controls, respectively.
