(Submitter supplied) Measles virus vector expressing the 4 reprogramming factors, OCT4, SOX2, KLF4 and cMYC was produced and used to derived iPSC from neonatal human fibroblasts (BJ). We used microarrays to compare the global gene expression in the derived MV-iPSC and compare it to the parental human neonatal fibroblast (BJ) and human embryonic stem cell (GSM551202)

(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) Oct4 is widely considered the most important among the four Yamanaka reprogramming factors. Here we show that the combination of Sox2, Klf4, and cMyc (SKM) suffices for reprogramming mouse somatic cells to induced pluripotent stem cells (iPSCs). Simultaneous induction of Sox2 and cMyc in fibroblasts triggers immediate retroviral silencing, which explains the discrepancy with previous studies that attempted but failed to generate iPSCs without Oct4 using retroviral vectors. 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 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...

Analysis of chimpanzee iPSCs generated from blood cells using Sendai virus vector TS12KOS which carries reprogramming factors KLF4, OCT3/4, and SOX2. TS12KOS was also used to establish human iPSCs from fibroblasts. Results examine differentially expressed genes between human and chimpanzee iPSCs.

(Submitter supplied) Induced pluripotent stem cells (iPSCs) can be derived from somatic cells by the introduction of the transcription factors Oct4, Sox2, Klf4 and cMyc using various methods. Here, we describe a new approach for the derivation of murine iPSCs using a polycistronic non-viral inducible vector integrated into pseudo attP sites via the C31 integrase-mediated site-specific recombination and subsequent vector excision by Cre recombinase. more...

(Submitter supplied) A variety of somatic cells can be reprogrammed to induced pluripotent stem cells (iPSCs), but the small number of CD34+ hematopoietic stem cells (HSCs) present in non-mobilized peripheral blood (PB) would be a convenient and desirable starting target. We report here a simple method for targeting derivation of iPSC from non-mobilized PB CD34+ HSCs using immunobead purification and 2-4 day culture to achieve enrichment of CD34+ HSCs to 80±9%, followed by reprogramming transduction with loxP-flanked polycistronic (Oct4, Klf4, Sox2, and c-Myc) STEMCCA-loxP lentivector at an MOI of 2. more...
