(Submitter supplied) Induced pluripotent stem (iPS) cells can be obtained through the introduction of defined factors into somatic cells. The combination of Oct4, Sox2 and Klf4 (OSK) constitutes the minimal requirement for generating iPS cells from mouse embryonic fibroblasts (MEFs). Through the genomic analyses of ESC genes that have roles in pluripotency and fusion-mediated somatic cell reprogramming, we identified Tbx3 as a transcription factor that significantly improves the quality of iPS cells. more...

(Submitter supplied) Induced pluripotent stem (iPS) cells can be obtained through the introduction of defined factors into somatic cells. The combination of Oct4, Sox2 and Klf4 (OSK) constitutes the minimal requirement for generating iPS cells from mouse embryonic fibroblasts (MEFs). These cells are thought to resemble embryonic stem cells (ESCs) based on global gene expression analyses; but, few studies have tested their ability and efficiency in contributing to chimerism, colonization of germ tissues, and most importantly, germ-line transmission and life-birth from iPS cells produced with tetraploid complementation. more...

(Submitter supplied) Low Klf4 expression reproducibly gives rise to a homogeneous population of partially reprogrammed iPSCs. Upregulation of Klf4 allows these cells to resume reprogramming, indicating that they are paused iPSCs that remain on the path towards pluripotency. Paused iPSCs with different Klf4 expression levels remain at distinct intermediate stages of reprogramming.

(Submitter supplied) We have generated “reprogrammable” transgenic mice that ubiquitously express the four Yamanaka factors in an inducible manner. Transitory induction of the transgene results in multiple teratomas emerging from a variety of organs, thus indicating that full reprogramming into iPSCs can occur in vivo. By performing bone marrow transplant experiments, we demonstrate that both hematopoietic cells, as well as non-hematopoietic cells can be reprogrammed in vivo. more...

(Submitter supplied) Reprogramming of somatic cells is a valuable tool to understand the mechanisms of regaining pluripotency and further opens up the possibility of generating patient-specific pluripotent stem cells. Reprogramming of mouse and human somatic cells into pluripotent stem cells, designated as induced pluripotent stem (iPS) cells, has been possible with the expression of the transcription factor quartet Oct4 (also known as Pou5f1), Sox2, c-Myc, and Klf4. 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...

(Submitter supplied) Differentiated cells can be reprogrammed to an embryonic-like state by transfer of their nuclear contents into oocytes or by fusion with embryonic stem (ES) cells. Little is known about the factors that induce this reprogramming. Here we show that the combination of four factors, Oct3/4, Sox2, c-Myc, and Klf4, can generate pluripotent-like stem cells directly from mouse embryonic or adult fibroblast cultures. more...

(Submitter supplied) Ectopic expression of four transcription factors including Oct4, Sox2, Klf4 and c-Myc in differentiated fibroblast cells could reset the cell fate of fibroblast cells to pluripotent state. Subsequently, fully pluripotency of these so-called induced pluripotent stem cells (iPSCs) has been demonstrated as viable mice could be generated autonomously from iPS cells through tetraploid blastocyst complementation. more...

(Submitter supplied) In the murine system, Oct4, Sox2, c-Myc and Klf4 are sufficient to convert fibroblasts to induced pluripotent stem (iPS) cells that exhibit many characteristics of embryonic stem (ES) cells. Herein, we show that the orphan nuclear receptor Esrrb works in conjunction with Oct4 and Sox2 to mediate reprogramming of mouse embryonic fibroblasts (MEFs) to iPS cells. Esrrb reprogrammed cells share similar expression and epigenetic signatures as ES cells. more...

(Submitter supplied) The pluripotency of mouse embryonic stem cells (ESC) and induced-pluripotent stem cells (iPSC) can be maintained by feeder cells, which secrete Leukemia Inhibitory Factor (LIF). We found that feeder cells provide a relatively low concentration (25 unit/ml) of LIF, which is insufficient to maintain the ESC/iPSC pluripotency in feeder free conditions. In order to identify additional factors involved in the maintenance of pluripotency, we carried out a global transcript expression profiling of mouse iPSC cultured on feeder cells and in feeder-free (LIF-treated) conditions. more...

(Submitter supplied) Embryonic stem cells (ESCs), which are derived from the primitive ectoderm of pre-implantation blastocysts, are pluripotent cells and can thus contribute to the formation of all somatic cell lineages in chimeric animals. Similarly, epiblast stem cells (EpiSCs), which are derived from epiblast tissue of post-implantation embryos, are also pluripotent and can give rise to derivatives of all three germ layers in teratoma assays. more...

(Submitter supplied) We report that the PRC1 component polycomb group ring finger 6 (Pcgf6) is required to maintain embryonic stem cell (ESC) identity. In contrast to canonical PRC1, Pcgf6 acts as a positive regulator of transcription and binds predominantly to promoters bearing active chromatin marks. Pcgf6 is expressed at high levels in ESCs, and knockdown reduces the expression of the core ESC regulators Oct4,Sox2, and Nanog. more...

(Submitter supplied) Nr5a2 (also known as liver receptor homolog-1, Lrh-1) has been shown to bind both the proximal enhancer and proximal promoter regions of Pou5f1 and regulate Pou5f1 in the epiblast stage of mouse embryonic development (Gu et al., 2005). Nr5a2-null embryos display a loss of Oct4 expression in the epiblasts (Gu et al., 2005) and die between E6.5 and E7.5 (Gu et al., 2005; Pare et al., 2004). To identify the targets of Nr5a2, we generated a stable ES cell-line that expresses HA-tagged Nr5a2. more...
