(Submitter supplied) During development, progenitors of embryonic stem (ES) and extraembryonic endoderm stem (XEN) cells are concomitantly specified within the inner cell mass (ICM) of the mouse blastocyst. Similarly, XEN cells are induced (iXEN cells) alongside induced pluripotent stem (iPS) cells following overexpression ofOct4,Sox2,Klf4andMyc(OSKM) during somatic cell reprogramming. It is unclear how or why this cocktail produces both stem cell types, but OCT4 has been associated with non-pluripotent outcomes. more...

(Submitter supplied) While the reprogramming factors OCT4, SOX2, KLF4, and MYC (OSKM) can reactivate the pluripotency network in terminally differentiated cells, they also regulate expression of non-pluripotency genes in other contexts, such as the mouse primitive endoderm. The primitive endoderm is an extraembryonic lineage established alongside the pluripotent epiblast in the blastocyst, and is the progenitor pool for extraembryonic endoderm stem (XEN) cells. more...

(Submitter supplied) Transcription factor-mediated reprogramming is a powerful method to study cell fate changes. In this work, we demonstrate that the transcription factor Gata6 can initiate reprograming of multiple cell types to induced extraembryonic endoderm (iXEN) cells. Intriguingly, Gata6 is sufficient to drive iXEN cells from mouse pluripotent cells and differentiated neural cells. Furthermore, GATA6 induction in human ES (hES) cells also downregulates pluripotency gene expression and upregulates extraembryonic endoderm genes, revealing a conserved function in mediating this cell fate switch. more...

DESCRIPTION: RNA-seq profiles of early reprogramming mouse embryonic fibroblasts (MEFs) transduced with lentivirus containing doxycycline-inducible OSKM factors to induce pluripotency . Before starting reprogramming, OSKM-MEFs were transfected with different siRNAs and then they were reprogrammed for 3 or 6 days.

(Submitter supplied) Resolution of early molecular events preceding endogenous OCT4 activation is critical to understanding the mechanism of reprogramming somatic cells to induced pluripotent stem cells (iPSCs), yet capturing transient regulators at the onset of reprogramming is difficult in heterogeneous populations of asynchronously reprogramming fibroblasts following four-factor transduction. To address this need, we used a heterokaryon system to identify an early and transiently expressed homeobox transcription factor, NKX3-1. more...

(Submitter supplied) We used heterokaryon cell fusion based reprogramming and identified the cytokine IL6 as a potential regulator of reprogramming to pluripotency. We generated iPS clones using the four reprogramming factors (4F) Oct4, Klf4, Sox2, and c-Myc. In addition, iPS clones were generated using only three factors (3F: Oct4, Klf4, amd Sox2) with the addition of the cytokine IL6 to reprogramming culture conditions. more...

(Submitter supplied) Embryo-like structures generated from stem cells can achieve varying developmental milestones, but none have been shown to progress through gastrulation, neurulation, and organogenesis. Here, we show that "ETiX" mouse embryoids, assembled from embryonic stem cells, trophoblast stem cells and inducible extraembryonic endoderm stem cells, can develop into gastrulating embryoids, and beyond to generate neurulating embryoids, which generate the progenitors needed to create the entire organism. more...

We find that all the cell types present in the natural embryos examined at these timepoints were also present in their synthetic counterparts. more...

(Submitter supplied) Derivation and maintenance of pluripotent stem cells (PSCs) including embryonic stem cells(ESCs) and (iPSCs) usually requires optimization of complex culture media, which hinders the generation of PSCs from various species. Expression of Oct4, Sox2, Klf4 and c-Myc (OSKM) can reprogram somatic cells into iPSCs, even for species possessing no optimal culture condition. Here we explored whether expression of OSKM could induce and maintain pluripotency without specific growth factors and signaling inhibitors. more...

(Submitter supplied) Differentiated somatic cells can be reprogrammed into induced pluripotent stem cells by ectopic expression of transcription factors Oct4, Sox2, Klf4, and c-Myc, but the mechanisms are still to be dissected. The stoichiometry of factors influences the efficiency of induced pluripotent stem cells, and previous studies emphasized the requirement of high levels of overexpressed Oct4. In this study, we showed that, with appropriate stoichiometry achieved by polycistronic cassettes, Sox2 and Klf4 were sufficient to initiate and establish pluripotency in differentiated cells efficiently without Oct4 overexpression.
