(Submitter supplied) We report the application of bi-species RNAseq for investigating mechanisms of reprogramming towards pluripotency using heterokaryons (mouse embryonic stem cell X human fibroblast cell fusions). The use of mixed species allows one to monitor reprogramming of the human somatic nuclei independently of contributions from the mouse nuclei using nucleotide differences. We used RNAseq to monitor heterokaryon reprogramming over a 3-day timecourse, generating transcriptome-wide data for cell fusion based reprogramming of human fibroblasts towards pluripotency.

(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) 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 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) Pluripotent stem cells are derived from culture of early embryos or the germline, and can be induced by reprogramming of somatic cells. Barriers to reprogramming are expected to exist that stabilize the differentiated state and have tumor suppression functions. However, we have a limited understanding of what such barriers might be. To find novel barriers to reprogramming to pluripotency, we compared the transcriptional profiles of the mouse germline to pluripotent and somatic cells, in vivo and in vitro. 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) 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) Reprogramming of somatic cells produces induced pluripotent stem cells (iPSCs) that are invaluable resources for biomedical research. Transcriptional and epigenetic changes have been investigated to facilitate our understanding of the reprogramming process.

(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...
