Induced pluripotent stem cells (iPSCs) can be derived from somatic cells by gene transfer of reprogramming transcription factors. Expression levels of these factors strongly influence the overall… (More)
The liver has adapted to the inflow of ingested toxins by the evolutionary development of unique regenerative properties and responds to injury or tissue loss by the rapid division of mature cells.… (More)
Directed endodermal differentiation of murine embryonic stem (ES) cells gives rise to a subset of cells with a hepatic phenotype. Such ES cell-derived hepatic progenitor cells (ES-HPC) can acquire… (More)
Heterogeneity among induced pluripotent stem cell (iPSC) lines with regard to their gene expression profile and differentiation potential has been described and at least partly linked to the tissue… (More)
Induced pluripotent stem cells (iPSCs) can be generated by overexpression of Oct4, Sox2 and Klf4 in murine fibroblasts. By conducting a microRNA (miRNA) library screen, we identified a set of miRNAs… (More)
Methylation-induced gene silencing represents a major obstacle to efficient transgene expression in pluripotent cells and thereof derived tissues. As ubiquitous chromatin opening elements (UCOE) have… (More)
Epigenetic silencing of retroviral transgene expression in pluripotent stem cells (PSC) and their differentiated progeny constitutes a major roadblock for PSC-based gene therapy. As ubiquitous… (More)
The POU-domain transcription factor OCT4 is associated with the pluripotent state of cells comprising the inner cell mass of pre-implantation embryos and has been known to play a critical role in the… (More)

Retroviral particles assemble a few thousand units of the Gag polyproteins. Proteolytic cleavage mediated by the retroviral protease forms the bioactive retroviral protein subunits before cell entry.… (More)
There has been recent progress in the isolation and characterisation of stem/progenitor cells that may differentiate towards the hepatic lineage. This has raised expectations that therapy of genetic… (More)
