Conversion of Mouse Fibroblasts to Sphere Cells with Differentiation Potential Induced by AlbuMAXI-containing Medium

ABSTRACT: Analysis of gene expression levels during Fibroblast to sphere cell conversion induced by albumax I containing medium. Murine embryonic fibroblasts (MEF) can be converted to sphere cells in the presence of arachidonic acid and pluronic - F 68. The converted cells exhibit stem cell like properties and and have the potential to differentiate into all the three embryonic germ layers. Our results provide important information on genes that are up- or down-regulated during the reprogramming/conversion process. Total RNA was isolated from murine embryonic fibroblasts, normal mouse embryonic stem (MES) cells and converted sphere cells. MES cells were taken as a control/reference population. Three replicated were included for each sample.

The expression profiles of genes using genetically modified parthenogenetic mouse embryonic stem cells

Project description:Embryonic stem (ES) cells are used in cell therapy and tissue engineering due to their ability to produce different cells types. However, studies of ES cells that are derived from fertilized embryos have raised concerns about the limitations imposed by ethical and political considerations. Therefore, many studies of ES cells use the ES cells that are derived from unfertilized oocytes and adult tissue. Although parthenogenetic embryonic stem (ESP) cells also avoided ethical and political dilemmas and can be used in cell-based therapy, the ESP cells exhibit growth retardation problems. Therefore, to investigate the potential for muscle growth from genetically modified ESP cells, we established four ES cell types, including normal embryonic stem (ESN) cells, ESP cells, ESP cells that overexpress the Igf2 gene (ESI) and ESP cells with down-regulated H19 gene expression (ESH). Using these cells, we examined the expression profiles of genes that were related to imprinting and muscle using microarrays. Total RNA obtained from isolated genetically modified parthenogenetic mouse embryonic stem cells compared to parthenogenetic mouse embryonic stem cells. 2 Biological Replication.

Serum Conditions Do Not Abolish The Tumorigenicity of Glioma Stem Cells

Project description:The subset of GBM patient samples gives rise to adherent cultures even in sphere culture conditions. Most samples in this subset are tumorigenic and exhibit a hybrid expression profile when tested with the marker panel. Cultures from these samples have a predominantly mesenchymal character based on substrate adherence, morphology, differentiation potential and gene expression. Total RNA isolated from glioblastoma stem cells (GSC) cultured as spheres was compared to that from adherent GSCs cultured in sphere culture conditions that exhibited both GSC and mesenchymal properties.

Systems biology approach to identify transcriptional reprogramming and microRNA targets during the progression of Polycystic Kidney Disease

Project description:Autosomal dominant polycystic kidney disease (ADPKD) is characterized by cyst formation throughout the kidney parenchyma. It is caused by mutations in either of two genes, PKD1 and PKD2. Mice that lack functional Pkd1 (Pkd1null/null), develop rapidly progressive cystic disease during embryogenesis, and serve as a model to study human ADPKD. We examined the molecular pathways that modulate renal cyst growth in the Pkd1null/null model by performing global gene-expression proﬁling in embryonic kidneys at day 14 and 17. Gene Ontology and gene set enrichment analysis were used to identify overrepresented signaling pathways in Pkd1null/null kidneys. We found dysregulation of developmental, metabolic, and signaling pathways (e.g. Wnt, calcium, TGF-b and MAPK) in Pkd1null/null kidneys. Total RNA were obtained from kidneys of wild-type and Pkd1null/null animals at embryonic ages 14.5 and 17.5.

Conversion of mES to cXEN cells

Project description:The inner cell mass of the mouse pre-implantation blastocyst is comprised of epiblast progenitor and primitive endoderm cells of which cognate embryonic (mESCs) or extra-embryonic (XEN) stem cell lines can be derived. Importantly, each stem cell type retains the defining properties and lineage restriction of their in vivo tissue of origin. Recently, we demonstrated that XEN-like cells arise within mESC cultures. This raises the possibility that mESCs can generate self-renewing XEN cells without the requirement for gene manipulation. We have developed a novel approach to convert mESCs to XEN cells (cXEN) using growth factors. We confirm that the down-regulation of the pluripotency transcription factor Nanog and the expression of primitive endoderm-associated genes Gata6, Gata4, Sox17 and Pdgfra are necessary for cXEN cell derivation. This approach highlights an important function for Fgf4 in cXEN cell derivation. Paracrine FGF-signalling compensates for the loss of endogenous Fgf4, which is necessary to exit mESC self-renewal, but not for XEN cell maintenance. Our cXEN protocol also reveals that distinct pluripotent stem cells respond uniquely to differentiation promoting signals. cXEN cells can be derived from mESCs cultured with Erk- and Gsk3-inhibitors (2i) and LIF, similarly to conventional mESCs. However, we find that epiblast stem cells (EpiSCs) derived from the post-implantation embryo are refractory to cXEN cell establishment, consistent with the hypothesis that EpiSCs represent a pluripotent state distinct from mESCs. In all, these findings suggest that the potential of mESCs includes the capacity to give rise to both extra-embryonic and embryonic lineages. A total of eight samples were analyzed. Three mouse embryonic stem cell (mESC) lines were used as a negative control, 2 embryo-derived extraembryonic endoderm (XEN) cell lines were used as a positive control, 3 converted XEN (cXEN) cells were used as the experiemental cell lines.

Metastable primordial germ cell-like state induced from mouse embryonic stem cells by Akt activation

Project description:Specification to primordial germ cells (PGCs) occurs under the mesoderm induction signals during gastrulation. Here, we found that Akt activation in embryonic stem (ES) cells generated self-renewing spheres during mesodermal differentiation induction and that the differentiation status of the sphere cells was in between ES cells and PGCs. Essential regulators for PGC specification and their downstream germ cell-specific genes were expressed in the spheres, showing that the cells of the sphere commenced the differentiation to germ lineage. However, the spheres could not proceed to spermatogenesis after transplantation to testes. Meanwhile, the transfer of the spheres to the original feeder-free ES cell culture conditions induced chaotic differentiation. In contrast, when the spheres were cultured on mouse embryonic fibroblasts or in the presence of ERK-cascade and GSK3 inhibitors, the reversion to the ES cell-like cell states was induced. These results indicate that the Akt signaling brings about a novel metastable and pluripotent state between ES cells and PGCs. Five samples were analyzed, which included the Akt-Mer-expressing ES cell (ESC) line #21 treated with or without 4OHT (4-hydroxytamoxifen), the #21 ESC-derived primordial germ cell (PGC)-like sphere cells and the ESC-like cells reverted from #21 PGC-like sphere cells. The PGC-like sphere cells derived from another Akt-Mer ESC line #42 was also examined.

Factors underlying variable DNA methylation in a human community cohort

Project description:Epigenetics is emerging as an attractive mechanism to explain the persistent genomic embedding of early-life experiences. Tightly linked to chromatin, which packages DNA into chromosomes, epigenetic marks primarily serve to regulate the activity of genes. DNA methylation is the most accessible and characterized component of the many chromatin marks that constitute the epigenome, making it an ideal target for epigenetic studies in human populations. Here, using peripheral blood mononuclear cells collected from a community-based cohort stratified for early-life socioeconomic status, we measured DNA methylation in the promoter regions of more than 14,000 human genes. Using this approach, we broadly assessed and characterized epigenetic variation, identified some of the factors that sculpt the epigenome, and determined its functional relation to gene expression.We found that the leukocyte composition of peripheral blood covaried with patterns of DNA methylation at many sites, as did demographic factors, such as sex, age, and ethnicity. Furthermore, psychosocial factors, such as perceived stress, and cortisol output were associated with DNA methylation, as was early-life socioeconomic status. Interestingly, we determined that DNA methylation was strongly correlated to the ex vivo inflammatory response of peripheral blood mononuclear cells to stimulation with microbial products that engage Toll-like receptors. In contrast, our work found limited effects of DNA methylation marks on the expression of associated genes across individuals, suggesting a more complex relationship than anticipated This cohort consist of genomic DNA extracted from 94 PBMC DNA samples, bisulphite converted and hybridized, along with 5 technical replicates to the Illumina Infinium HumanMethylation27 Beadchip v1.2 for genome wide DNA methylation profiling.

Reprogramming-associated aberrant DNA methylation determines hematopoietic differentiation capacity of human induced pluripotent stem cells [undiff_iPSESCs_methylation]

Project description:The variation among induced pluripotent stem cells (iPSCs) in their differentiation capacity to specific lineages is frequently attributed to somatic memory. In this study, we compared hematopoietic differentiation capacity of 35 human iPSC lines derived from four different tissues and four embryonic stem cell lines. The analysis revealed that hematopoietic commitment capacity (PSCs to hematopoietic precursors) is correlated with the expression level of the IGF2 gene independent of the iPSC origins. In contrast, maturation capacity (hematopoietic precursors to mature blood) is affected by iPSC origin; blood-derived iPSCs showed the highest capacity. However, some fibroblast-derived iPSCs showed higher capacity than blood-derived clones. Tracking of DNA methylation changes during reprogramming reveals that maturation capacity is highly associated with aberrant DNA methylation acquired during reprogramming, rather than the types of iPSC origins. These data demonstrated that variations in the hematopoietic differentiation capacity of iPSCs are not attributable to somatic memories of their origins. Bisulfite converted genomic DNA lysates from induced pluripotent stem cellã??and embryonic stem cell lines were hybridized to Illumina HumanMethylation450 BeadChip.
