Project description:Somatic cells can be reprogrammed to Induced Pluripotent Stem Cells (iPSCs) by expressing four transcription factors, Oct4, Sox2, Klf4 and c-Myc. Co-expressing Rarg (retinoic acid receptor gamma) and Lrh-1 (liver receptor homolog 1, Nr5a2) with the four factors greatly accelerated reprogramming so that reprogramming of mouse embryonic fibroblast cells (MEFs) to ground state iPSCs requires only four days’ induction of these six factors. The six-factor combination readily reprogrammed primary human neonatal and adult fibroblast cells to exogenous-factor-independent iPSCs, which resembled ground state mouse ES cells in growth properties, gene expression and signalling dependency. Our findings demonstrate that signalling through RARs has critical roles in molecular reprogramming and the synergistic interaction between Rarg and Lrh1 directs reprogramming towards ground state pluripotency. SH-iPS20-1, -3 and -9 lines were derived from HDFa (439656), SH-iPS24-1, -2 and -11 lines were derived from HDFa (709590), and SH-iPS28-23, -25 and -27 lines were derived from HDFn (617769). Parental HDF lines were used as control. SH-iPS15-5 and -10 lines were derived from HDFn (617769, Invitrogen). H1 hESC were obtained from Wicell (Madison, USA). SH-iPSCs were cultured in both 2i+LIF and FGFconditions. Expression pattern of SH-iPSCs was compared to H1 hESC cultured in FGF conditions. S1, S2 and S3 are three indpendent subcultures of a cell line.

Project description:During reprogramming of mouse embryonic fibroblast, pluripotent genes are up-regulated. Once iPSCs are successfully reprogrammed, the global gene profiles of iPSCs are comparable to mouse ESC. We used microarrays to detail the global programme of gene expression in iPSCs, mESCs, MEFs.

Project description:We compared the exactly syngeneic ntESCs and iPSCs with same genomic insertion generated from adipocyte progenitor cells (APCs) isolated from the all-iPSC mice through the primary TF mediated reprogramming by performing the high-throughput sequencing. There were 84 genes significantly upregulated in fully reprogrammed ntESCs compared with partially reprogrammed ntESCs and 391 genes upregulated in fully reprogrammed iPSCs compared with partially reprogrammed iPSCs. An overlapping gene, Grb10, was identified to associate with the pluripotency state of ntESCs.

Project description:Klinefelter’s Syndrome (KS) is one of the common chromosome aneuploidy diseases in males with unexplained physiological mechanism. iPSCs, are similar to ESCs in terms of indefinitive self-renewal and pluripotency, provided an alternative choice for modeling disease to facilitate the disease research in vitro. We used microarray to detect the global reprogramming of KS and normal fibroblast cells to iPSCs. Also we used microarray to explore the possible molecular varieties between KS patient and normal person in the early development. Fibroblast cells from both normal person and KS patient were reprogrammed into iPSCs by ectopic expression of OCT4, SOX2, KLF4 and C-MYC. The expression profiles of normal and KS fibroblast cells, a line of normal iPSCs and two lines of KS iPSCs as well as a line of human ESCs were detected.

Project description:Standardization of mesenchymal stromal cells (MSCs) remains a major obstacle in regenerative medicine. Starting material and culture expansion affect cell preparations and render comparison between studies difficult. In contrast, induced pluripotent stem cells (iPSCs) assimilate towards a ground-state and may therefore give rise to more standardized cell preparations. We reprogrammed bone marrow MSCs into iPSCs which were subsequently re-differentiated towards MSCs. These iPS-MSCs revealed similar morphology, immunophenotype, in vitro differentiation potential, and gene expression profiles as primary MSCs. DNA methylation (DNAm) profiles of iPSCs maintained some donor-specific characteristics, whereas tissue-specific, senescence-associated, and age-related DNAm patterns were erased during reprogramming. iPS-MSCs reacquired senescence-associated DNAm during culture expansion but they remained rejuvenated with regard to age-related DNAm. Overall, iPS-MSCs and MSCs are similar in function but differ in their epigenetic makeup. 8 samples were hybridized to the GeneChip Human Gene 1.0 ST Array (Affymetrix)

Project description:It remains controversial whether the routes from differentiated cells to iPSCs are related to the reverse order of normal developmental processes or independent of them. Here, we generated iPSCs from mouse astrocytes by three (Oct3/4, Klf4 and Sox2 (OKS)), two (OK), or four (OKS plus c-Myc) factors. Sox1, a neural stem cell (NSC)-specific transcription factor, is transiently upregulated during reprogramming and Sox1-positive cells become iPSCs. The upregulation of Sox1 is essential for OK-induced reprogramming. Genome-wide analysis revealed that the gene expression profile of Sox1-expressing intermediate-state cells resembles that of NSCs. Furthermore, the intermediate-state cells are able to generate neurospheres, which can differentiate into both neurons and glial cells. Remarkably, during MEF reprogramming, neither Sox1 upregulation nor an increase in neurogenic potential occurs. Thus, astrocytes are reprogrammed through an NSC-like state, suggesting that reprogramming partially follows the retrograde pathway of normal developmental processes. To investigate the gene expression profile of intermediate-state cells during astrocyte reprogramming, we performed genome-wide gene expression analysis in five samples; starting astrocytes, intermediate-state cells expressing Sox1-GFP, NSCs, iPSCs established from astrocytes, and iPSCs established from MEFs (iPS-MEF-Ng-20D-17) that had previously been reported (Okita, K. et al. Nature 448: 313-317 (2007)). Two (NSCs, iPSCs from astrocytes and MEFs) or three (astrocytes, intermediate-state cells) biological replicates were prepared for microarray samples. Total RNA was extracted with an RNeasy kit (Qiagen). cDNA synthesis and transcriptional amplification were performed using 50-100 ng of total RNA with the GeneChip WT PLUS Reagent Kit (Affymetrix). Fragmented and biotin-labeled cDNA targets were hybridized to GeneChip Mouse Gene 1.0 ST arrays (Affymetrix) according to the manufacturerâ??s protocol. Hybridized arrays were scanned using an Affymetrix GeneChip Scanner.

Project description:The differentiation capability of induced pluripotent stem cells (iPSCs) towards certain cell types for disease modelling and drug screening assays might be influenced by their somatic cell of origin. Here, we have compared the neural induction of human iPSCs generated from either fetal neural stem cells (fNSCs), dermal fibroblasts or CD34+ hematopoietic stem cells. Neural progenitor cells (NSCs) and neurons could be generated at similar efficiencies from all iPSCs. Whole genome transcriptome analysis and an expression analysis of neural genes in iPSC-derived NSCs revealed a separation of neuroectoderm- from mesoderm-derived cells. Furthermore, we found genes, which were similarly expressed between fNSCs and neuroectoderm- but not mesoderm-derived NSCs. Notably, these neural signatures were retained after transplantation into the cortex of mice and paralleled with increased survival and integration of neuroectoderm-derived cells in vivo. These results indicated distinct origin- dependent neural cell identities in differentiated human iPSCs both in vitro and in vivo. RNA samples for microarray analysis were prepared using RNeasy columns (Qiagen, Germany) with on-column DNA digestion. 300 ng of total RNA per sample were used as the input in the linear amplification protocol (Ambion), which involved the synthesis of T7-linked double-stranded cDNAs and 12hrs of in vitro transcription incorporating biotin-labeled nucleotides. Purified and labeled cRNA was then hybridized for 18 hrs onto HumanHT-12 v4 expression BeadChips (Illumina, USA) following the manufacturer's instructions. After the recommended washing, the chips were stained with streptavidin-Cy3 (GE Healthcare) and scanned using the iScan reader (Illumina) and the accompanying software. The samples were exclusively hybridized as biological replicates. The RNA samples from in vivo transplanted and FACS sorted cells were amplified using the TargetAmp 2-Round Biotin-aRNA Amplification Kit 3.0 (Epicentre, USA) from 100 pg to 50 microg. 43 samples were analyzed Fib, Human fibroblast F134, 2 replicates CD34+, Human Cord Blood CD34+ Hematopoyetic Stem Cell (HSC), 1 replicate fNSC, Human fetal Neural Stem Cells (NSC), 1 replicate fNSC-1FiPSCa-NSC, Human one factor (POU5F1) fetal Neural Stem Cell (NSC) induced reprogrammed cell (iPSC) clone a, in vitro differentiated to NSC, 2 replicates fNSC-1FiPSCb-NSC, Human one factor (POU5F1) fetal Neural Stem Cell (NSC) induced reprogrammed cell (iPSC) clone b, in vitro differentiated to NSC, 2 replicates fNSC-2FiPSCa-NSC, Human two factors (POU5F1, KLF4) fetal Neural Stems Cell (NSC) induced reprogrammed cell (iPSC) clone a, in vitro differentiated to NSC, 2 replicates CD34-2FiPSCa-NSC, Human two factors (POU5F1, KLF4) cord blood CD34+ Hematopoyetic Stem Cell (HSC) induced reprogrammed cell (iPSC) clone a, in vitro differentiated to NSC, 2 replicates CD34-4FiPSCa-NSC, Human four factors (POU5F1, KLF4, SOX2, CMYC) cord blood CD34+ Hematopoyetic Stem Cell (HSC) induced reprogrammed cell (iPSC) clone a, in vitro differentiated to NSC, 2 replicates CD34-4FiPSCb-NSC, Human four factors (POU5F1, KLF4, SOX2, CMYC) cord blood CD34+ Hematopoyetic Stem Cell (HSC) induced reprogrammed cell (iPSC) clone b, in vitro differentiated to NSC, 2 replicates Fib-4FiPSCa-NSC, Human four factors (POU5F1, KLF4, SOX2, CMYC) fibroblast induced reprogrammed cell (iPSCs) clone a, in vitro differentiated to NSC, 2 replicates Fib-4FiPSCb-NSC, Human four factors (POU5F1, KLF4, SOX2, CMYC) fibroblast induced reprogrammed cell (iPSCs) clone b, in vitro differentiated to NSC, 2 replicates Fib-4FiPSCc-NSC, Human four factors (POU5F1, KLF4, SOX2, CMYC) fibroblast induced reprogrammed cell (iPSCs) clone c, in vitro differentiated to NSC, 1 replicate H1-ESC-NSC, Human H1 embryonic stem cell (ESC), in vitro differentiated to NSC, 2 replicates HUES6-ESC-NSC, Human HUES6 embryonic stem cell (ESC), in vitro differentiated to NSC, 1 replicate fNSC-1FiPSCa, Human one factor (POU5F1) fetal Neural Stem Cell (NSC) induced reprogrammed cell (iPSC) clone a, 1 replicate fNSC-1FiPSCb, Human one factor (POU5F1) fetal Neural Stem Cell (NSC) induced reprogrammed cell (iPSC) clone b, 1 replicate fNSC-2FiPSCa, Human two factors (POU5F1, KLF4) fetal Neural Stems Cell (NSC) induced reprogrammed cell (iPSC) clone a, 1 replicate CD34-2FiPSCa, Human two factors (POU5F1, KLF4) cord blood CD34+ Hematopoyetic Stem Cell (HSC) induced reprogrammed cell (iPSC) clone a, 1 replicate CD34-4FiPSCa, Human four factors (POU5F1, KLF4, SOX2, CMYC) cord blood CD34+ Hematopoyetic Stem Cell (HSC) induced reprogrammed cell (iPSC) clone a, 1 replicate CD34-4FiPSCb, Human four factors (POU5F1, KLF4, SOX2, CMYC) cord blood CD34+ Hematopoyetic Stem Cell (HSC) induced reprogrammed cell (iPSC) clone b, 1 replicate Fib-4FiPSCa, Human four factors (POU5F1, KLF4, SOX2, CMYC) fibroblast induced reprogrammed cell (iPSCs) clone a, 1 replicate Fib-4FiPSCb, Human four factors (POU5F1, KLF4, SOX2, CMYC) fibroblast induced reprogrammed cell (iPSCs) clone b, 1 replicate H1-ESC, Human H1 embryonic stem cell (ESC), 3 replicates HUESC6-ESC, Human HUESC6 embryonic stem cell (ESC) , 2 replicates Fib-4FiPSCa-NSC-In Vivo, Human four factors (POU5F1, KLF4, SOX2, CMYC) fibroblast induced reprogrammed cell (iPSCs) clone a, in vivo differentiated to NSC, 2 replicates fNSC-1FiPSCa-NSC-In Vivo, Human one factor (POU5F1) fetal Neural Stem Cell (NSC) induced reprogrammed cell (iPSC) clone a, in vivo differentiated to NSC, 4 replicates

Project description:Pig induced pluripotent stem cells (piPSCs) have significant biomedical and agricultural applications. We analyzed the transcriptional profiles of pig iPSC lines derived from different labs using Affymetrix GeneChip Pig Genome Array and published microarray datasets of mouse and human iPSCs. Our results demonstrated that cell surface proteins of EpCAM (epithelial cells adhesion molecule) were significantly upregulated in complete fully reprogrammed pig iPSCs, but not in partially reprogrammed cells. EpCAM could be markers for evaluating pig cell reprogramming and selecting successful reprogramming. We analyzed gene expression levels of the six key developmental signaling pathways, including JAK-STAT, NOTCH, TGF-M-NM-2b, WNT, MAPK and VEGF in pig, human and mouse iPSCs, respectively. The result demonstrates that the core transcriptional network to maintain pluripotency and self-renewal in pig are different from mouse and human. Pig iPSCs lacked expression of specific naM-CM-/ve state markers (e.g. Klf family genes Klf2/4/5, Tbx3), but expressed unregulated primed state markers (e.g. Otx2 and Fabp7). Dlk1-Dio3 domain was silenced in piPSCs as previously seen in mouse and human iPSCs, which explantsexplains rare success of generation of pig chimeric and cloned offspring. Our analyses decipher pig somatic cells undergoes reprogramming into a primed state and maintains its regulatory network with define feature with human iPSCs and mouse EpiSCs. We compare gene expression profiles of pig iPS cell lines generated by our lab with cell lines derived from other labs with different levels of marker expression and plasticity.
