(Submitter supplied) Small-molecule based lineage reprogramming has newly emerged as a promising approach for generating functional cell types. We recently found that the chemical induction of iPSCs from fibroblasts pass through an extra-embryonic endoderm (XEN)-like state. In this study, we demonstrated that these chemically-induced XEN-like cells were not restricted to be reprogrammed to iPSCs, but feasible to be induced into functional neurons, bypassing the pluripotent stage. more...

(Submitter supplied) Fibroblasts can be chemically induced to pluripotent stem cells (CiPSCs) through an extraembryonic endoderm (XEN)-like state or directly converted into other differentiated cell lineages. However, the mechanisms underlying chemically-induced cell fate reprogramming remain unclear. Here, a transcriptome-based screen of biologically active compounds uncovered that CDK8 inhibition was essential to enable chemically-induced reprogramming from fibroblasts into XEN-like cells, then CiPSCs. more...

(Submitter supplied) The visceral endoderm (VE) is an epithelial tissue in the early postimplantation mouse embryo that encapsulates the pluripotent epiblast distally and the extraembryonic ectoderm proximally. In addition to facilitating nutrient exchange before the establishment of a circulation, the VE is critical for patterning the epiblast. Since VE is derived from the primitive endoderm (PrE) of the blastocyst, and PrE-derived eXtraembryonic ENdoderm (XEN) cells can be propagated in vitro, XEN cells should provide an important tool for identifying factors that direct VE differentiation. more...

(Submitter supplied) Somatic cells can be chemically reprogrammed into a pluripotent stem cell (CiPSC) state, mediated by an extraembryonic endoderm- (XEN-) like state. We found that the chemical cocktail applied in CiPSC generation initially activated a plastic state in mouse fibroblasts before transitioning into XEN-like cells. The plastic state was characterized by broadly activated expression of development-associated transcription factors (TFs), such as Sox17, Ascl1, Tbx3, and Nkx6-1, with a more accessible chromatin state indicating an enhanced capability of cell fate conversion. more...

(Submitter supplied) Mouse somatic cells can be chemically reprogrammed into pluripotent stem cells (CiPSCs) through an intermediate extraembryonic endoderm (XEN)-like state. However, it is elusive how the chemicals orchestrate the cell fate alteration. In this study, we analyze molecular dynamics in chemical reprogramming from fibroblasts to a XEN-like state. We find that Sox17 is initially activated by the chemical cocktails, and XEN cell fate specialization is subsequently mediated by Sox17 activated expression of other XEN master genes, such as Sall4 and Gata4. more...

(Submitter supplied) Pluripotent stem cells can be generated by pure small molecule compounds. However, only fibroblasts, a heterogeneous cell population, were reported for use in chemical reprogramming, and the efficiency is relatively low, raising the possibility that chemically induced pluripotent stem cells (CiPSCs) are derived from a specific cell subpopulation residing in fibroblast culture. Thus, it is of interest to know whether chemical reprogramming can be induced in other cell types, even using the same chemical cocktail. more...

(Submitter supplied) Recent advances have suggested that direct induction of neural stem cells could provide an alternative to derivation from somatic tissues or pluripotent cells. Here we show direct derivation of stably expandable NS cells from mouse fibroblasts through a curtailed version of reprogramming to pluripotency. By constitutively inducing Sox2, Klf4, and c-Myc while strictly limiting Oct4 activity to the initial phase of reprogramming, we generated neurosphere-like colonies that could be expanded for more than 50 passages and do not depend on sustained expression of the reprogramming factors. more...

(Submitter supplied) Recently, direct reprogramming between divergent lineages has been achieved by introducing cell-fate-determining transcription factors. This progress may provide alternative cell resources for drug discovery and regenerative medicine. However, the genetic manipulation may limit the future application of these approaches. In this study, we identified a novel small-molecule cocktail that directly converted fibroblasts into neuronal cell fate with a high yield up after 16-days of induction. more...

(Submitter supplied) In this study we showed that rat XEN cells grown in the presence of a GSK3 inhibitor exhibited enhanced formation of cell contacts and decreased motility. In contrast, treatment with forskolin induced the PE formation and epithelial-mesenchymal transition (EMT) in rat XEN cells. Using microarray and real-time PCR assays, we found that VE versus PE formation of rat XEN cells was correlated with change in expression levels of VE or PE marker genes. more...

(Submitter supplied) Reprogramming of somatic cells provides potential for the generation of specific cell types, which could be a key step in the study and treatment of human diseases. In vitro reprogramming of somatic cells into a pluripotent embryonic stem (ES) cell–like state has been reported by retroviral transduction of murine fibroblasts using four embryonic transcription factors or through cell fusion of somatic and pluripotent stem cells. more...

We start by converting mouse embryonic fibroblasts (MEFs) to epithelial-like cells (ciELC) with chemicals and growth factors. Subsequent cell fate mapping reveals a robust induction of SOX17 in the resulting ELCs that can be further reprogrammed to endodermal progenitor cells (ciEPC). more...
