Characterization of Definitive Endoderm formation from HESC and iPSC lines by Microarray analysis

ABSTRACT: HESC-H9 and iPSC lines 3.5, 3.6 and 3.12 were analyzed using Affymetrix microarray before and after Definitive Endoderm (DE) formation. DE was induced using the ActivinA differentiation protocol described by D'Amour et al., 2006 (PMID: 16258519) Clustering analysis of transcripts that were differentially regulated during DE formation indicated that iPSC lines 3.5 and 3.12 differentiate in manner that is highly similar to HESC-H9 cells iPSC line 3.6 had a more divergent transcriptional profile.

DE was induced using the ActivinA differentiation protocol described by D'Amour et al., 2006 (PMID: 16258519) Clustering analysis of transcripts that were differentially regulated during DE formation indicated that iPSC lines 3.5 and 3.12 differentiate in manner that is highly similar to HESC-H9 cells iPSC line 3.6 had a more divergent transcriptional profile. Three induced pluripotent stem cell lines (iPSC) and one human embryonic stem cell line (hESC - H9) were collected as undifferentiated (UD) cells, and flash frozen. These cell lines were also subjected to definitive endoderm (DE) induction, collected and flash frozen. RNA was harvested from the frozen cell pellets and hybridized to the Affymetrix microarray chip. The three iPSC cell lines are iPSC 3.5, iPSC 3.6. and iPSC 3.12. In the UD state, iPSC 3.5 was analyzed in duplicate, while iPSCs 3.6 and 3.12 and H9s were analyzed in biological triplicate. All four cell lines were analyzed as biological triplicates for DE induction.

Synergism between Activin A and BMP4 in directing the formation of definitive endoderm in human embryonic stem cells

Project description:Human embryonic stem cells (HESCs) herald tremendous promise for the production of clinically useful cell types for the treatment of injury and disease. Numerous reports demonstrate their differentiation into definitive endoderm (DE) cells, the germ layer from which pancreatic β cells and hepatocytes arise, solely from exposure to a high dose of recombinant Activin/Nodal. Here, we show that combining a second related ligand, BMP4, in combination with Activin A yields 15 to 20% more DE as compared to Activin A alone. The addition of recombinant BMP4 accelerates the downregulation of pluripotency factors, particularly SOX2, and results in upregulation of endogenous BMP2 and BMP4, which in turn leads to elevated levels of phospho-SMAD1/5/8 over the next three days of differentiation. Combined Activin A and BMP4 treatment also leads to an increase in the expression of DE genes CXCR4, SOX17 and FOXA2 when compared to Activin A addition alone. Comparative microarray studies between DE cells harvested on day 3 of differentiation further reveal a novel set of genes upregulated in response to initial BMP4 exposure. Several of these, including APLNR, LRIG3, MCC and LZTS1, are expressed either in the mouse primitive streak, the site of DE formation, or in nascent DE itself. Thus, this synergism between Activin A and BMP4 during the in vitro differentiation of HESC into DE suggests a complex interplay between BMP and Activin/Nodal signaling during the in vivo allocation and expansion of the endoderm lineage. 3 biological replicates of 3-day ActivinA treated HES3 human stem cell culture were compared to 3-day ActivinA+Bmp4 treated HES3 human stem cell culture and observed for differential genes expression

OGA-mediated protein glycosylation regulates pluripotency states in human embryonic stem cells

Project description:In our previous study, we uncovered that OGA significantly elevated in naïve hESC. Therefore, we sought to investigate the effects of O-GlcNAc on hESC and the interconvert of both pluripotent states. Depletion of OGA, which results in global O-GlcNAcylation increased, would impair naïve hESC pluripotency but can promote naïve to primed hESC transition. In addition, we obtained the profiles of O-GlcNAcylated proteins in H9 primed hESC and H9-PXGL hESC via MS based-quantitative proteomics.

MicroRNA expression data from differentiation of human H9 ESCs into definitive endoderm on MEF feeder layers

Project description:Pluripotent hESCs can differentiate into the three primary embryonic lineages (endoderm, mesoderm, ectoderm) as well as extraembryonic tissues. Definitive endoderm (DE) is the first step into the pathway to endoderm dreived tissues (pancreas, liver, gut, lung). We used microarrays to detail the changes in microRNA expression during the transition from pluripotent hESCs into definitive endoderm. hESCs (H9) were differentiated in the presence of Activin A and Wnt3A under low serum conditions to induce DE formation. Samples were collected at day 0 (hESCs), and day 4 (DE).

Global gene expression in patient keratinocytes and patient-specific iPS-derived keratinocytes

Project description:Patients with recessive dystrophic epidermolysis bullosa (RDEB) lack functional Type VII collagen and suffer severe blistering and chronic wounds that ultimately lead to infection and development of lethal squamous cell carcinoma (SCC). The discovery of induced pluripotent stem cells (iPSCs) and the ability to edit the genome bring the possibility to provide definitive genetic therapy through corrected autologous tissues. We have formed a multidisciplinary team with the ultimate goal to develop an iPSC-based therapy for RDEB. Here, we present a clinical protocol that generates autologous, corrected epithelial keratinocyte sheets with the COL7A1 gene mutation corrected for grafting on to patients. We demonstrate the utility of sequential reprogramming and novel adenovirus-associated viral genome editing to generate corrected iPSC banks. iPSC-derived keratinocytes were produced with minimal heterogeneity and secreted wild-type collagen VII, resulting in stratified epidermis in vitro and in vivo in mice. Sequencing of corrected cell lines prior to tissue formation revealed heterogeneity of SCC-predisposing mutations, allowing us to select COL7A1 corrected banks with minimal mutational burden for downstream epidermis production. Our results provide a first clinical platform to use iPSCs in the treatment of debilitating genodermatoses. Microarray analysis of iPS-derived keratinocytes from two RDEB patients (iPS-K1 and iPS-K3), corresponding patient keratinocytes (AHK1 and AHK2), normal human keratinocytes (NHK), as well as H9 human embryonic stem cells (hESC - H9). All samples were analyzed in duplicate and differential gene expression was measured relative to H9.

Different propensity in hematopoietic differentiation potential among distinct human pluripotent stem cell lines

Project description:Lineage-specific differentiation potential varies among different human pluripotent stem cell (hPSC) lines. A stem cell bank may advice researchers on which hPSCs exhibit the highest differentiation potential for a certain lineage. In this study, we aimed at characterizing the hematopoietic differentiation potential from 14 hESC/iPSC lines through the embryoid body (hEB) differentiation system. We carried out gene expression profiling on six different hESC lines grouped according to their ability to differentiate towards hematopoietic lineage: SHEF1, AND1 and H1 were considered as good (high CD45 expression and high CFU potential), whereas H9, HS181 and VAL3 were selected as poor-blood differentiating lines (low CD45 expression and low CFU potential). Human ESC samples were collected during the exponential cell growth phase and stabilized in RNA later. 500 ng of each total RNA sample was labelled with Cy3 using the Quick-Amp Labelling kit and hybridized with the Gene Expression Hybridization kit to a Whole Human Genome Oligo Microarray (Agilent Technologies) following the Manufacturer’s instructions. Each cell line was analyzed as independent duplicates. H9 hESC line was used as the baseline.
