Description
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.
Publication Title
Manipulation of KLF4 expression generates iPSCs paused at successive stages of reprogramming.

Description
We investigated roles of KRAS on stemness maintenance and differentiation propensity in the context of induced pluripotent stem cells (iPSCs) using isogenic KRAS mutant (G13C/WT) and wild-type (WT/WT) iPSCs from the same RAS-associated autoimmune lymphoproliferative syndrome-like disease (RALD) patients. RNA-seq analysis was conducted to compare gene expression profiles of WT/WT and G13C/WT iPS cells after in vitro differentiation. We found some differences of gene expression profiles regarding stemness and linage markers in the two genotypes. Overall design: To investigate the changes of stemness and linage markers between KRAS mutant and wild-type iPSCs after differentiation, the iPSCs were differentiated for 16 days . Two clones were used for each genotype (WT/WT and G13C/WT) before and after differentiation, resulting in total 8 conditions.

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
We have found that histone H2B is GlcNAcylated at residue S112 by O-GlcNAc transferase and that H2B S112 GlcNAcylation fluctuates in response to extracellular glucose level. We have also found that H2B S112 GlcAcylation promotes H2B K120 ubiquitination. To investigate whether these histone modification correlate to transcriptional activation, we performed comprehensive gene expression analysis using Affymetrix GeneChip in HeLa cell cultured with different conditions, i.e. without glucose, with glucose and with FBS.

Description
In order to find the difference between human lung tissue-derived fibroblasts and human vascular adventitial fibroblasts for enhancing tumor formation ablity of human lung adenocarcinoma cell line A549, we found that human vascular adventitial fibroblasts enhance A549 tumor formation in vivo compared to human lung tissue-derived fibroblasts. To find the responsible genes for this phenomena, we used microarray analysis to find the expression difference between lung tissue-derived fibroblasts and vascular adventitial fibroblas

Description
Splicing profiles in pluripotent stem cells are different from those in somatic cells. Generally, alternative splicing is regulated by RNA binding proteins. To identify the candidate RNA-binding protein-encoding genes, we performed gene expression profiling experiments.

Description
The generation of properly functioning gametes in vitro, a key goal in developmental/reproductive biology, requires multi-step reconstitutions of complex germ cell development. Based on the logic of primordial germ cell (PGC)-specification, we demonstrate here the generation of PGC-like cells (PGCLCs) in mice with robust capacity for spermatogenesis from embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) through epiblast-like cells (EpiLCs), a cellular state highly similar to pre-gastrulating epiblasts, but distinct from epiblast stem cells (EpiSCs). The global transcription profiles, epigenetic reprogramming, and cellular dynamics during PGCLC induction from EpiLCs are a meticulous capture of those associated with PGC specification from the epiblasts. Furthermore, we identify Integrin-beta 3 and SSEA1 as markers that purify PGCLCs with spermatogenic capacity free from tumorigenic undifferentiated cells. With the reconstitution of PGC specification pathway from the naive inner cell mass state, our study defines a paradigm for the essential step of in vitro gametogenesis.
