Project description:Occupancies of promoters by TBP, PolII, TFIIB as well as chromatin marks H3K4Me3 and H3K27ac were compared in embryonic stem cells (ESC) and in embryoid bodies (EB) treated with retinoic acid (RA) derived from the WT and Taf4a-/- lineages. Reduced occupancies for these factors and decreased signals for H3K4Me3 and H3K27ac were observed for genes associated with neuronal differentiation in EB of Taf4a-/- line compared to EB of WT line.

Project description:Differentiation of INSGFP/w hESCs using published protocols demonstrated that all GFP+ cells co-expressed insulin, confirming the fidelity of the reporter gene. INS-GFP+ cells also co-expressed glucagon and somatostatin, confirming prior studies regarding the polyhormonal nature of early hESC derived insulin-expressing cells. INSGFP/w hESCs were employed to develop a 96 well format spin Embryoid Body (EB) differentiation protocol that utilized the recombinant protein based fully defined medium, APEL. Like INS-GFP+ cells generated with other methods, those derived using the spin EB protocol expressed a collection of pancreatic related transcription factors including ISL1, PAX6 and NKX2.2. However, in contrast to previous methods, the spin EB protocol yielded INS-GFP+ cells that also co-expressed the beta-cell transcription factor, NKX6.1 and comprised a substantial proportion of monohormonal insulin+ cells.

Project description:Nicotine, the main constituent of tobacco, is highly detrimental to the developing fetus by increasing the risk of gestational complications and organ disorders. The effects of nicotine on human embryonic development and related mechanisms, however, remain largely unresolved. Here, we performed single-cell RNA-sequencing (scRNA-seq) of human embryonic stem cell (hESC)-derived embryoid body (EB) in the presence or absence of nicotine. Nicotine induced lineage-specific responses and dysregulated cell-to-cell communication in EBs, shedding light on the adverse effects of nicotine on human embryonic development. Additionally, nicotine reduced cell viability, increased reactive oxygen species (ROS), and altered cell cycling in EBs. Abnormal Ca2+ signaling was found in muscle cells upon nicotine exposure and verified in hESC-derived cardiomyocytes. Consequently, our scRNA-seq data suggests direct adverse effects of nicotine on hESC differentiation at the single-cell level and offers new method for evaluating drug and environmental toxicity on human embryonic development in utero.

Project description:Human Primordial Germ Cell (PGC)-like cells (PGCLC) were specified in vitro from naive-like hiPS cell lines. To evaluate the first steps of PGCLC differentiation, we performed scRNA-seq (droplet-based technology, 10x) on cell suspension from embryoid body (EB) obtained after EB aggregation followed by 4 days of culture (EBd4) with cocktail of cytokines (BMP4, LIF, SCF, EGF and ROCK inhibitor) supplemented with 0.1 mM 2-mercaptoethanol and 15% KSR. In this study, two pools of embryoid bodies (EBD4_A, EBD4_B) were cultured independently for for further encapsulation and sequencing.

Project description:Stem cell differentiation strategies and optimization for generating lineage-specific cells and tissues most frequently rely on a three-dimensional embryoid body (EB) intermediate. We previously applied nanotechnology tools of photolithography to generate custom microarrays that allow high throughput uniform formation of EBs of custom size for precise downstream analysis. Formation of EBs of 200 or 500 micron size revealed distinct morphological differences that are single or multicystic cores, respectively, independent of method of formation from single cells or two-dimensional (2D) clusters. Here we utilize photolithographic array generated EBs to obtain 3D cultures under a standardized platform for transcriptome analysis to compare EB size and the method of EB formation from single cells or mechanically passaged 2D clusters. Our analysis evaluates RNA expression in EBs formed from the human embryonic stem cell (hESC) line WA09 and from ethnically diverse human induced pluripotent stem cell lines (ED-iPSC) of African American and Hispanic Latino ethnicity recently derived in our laboratory. This is the first comprehensive study on EB transcriptomes including multiple size parameters, EB formation methodologies, and ethnicities. Our analysis indicates upregulation of genes involved in wound healing for mechanically passaged cells and of genes for embryonic tube formation in 500 micron multicystic EBs. We propose that EB maturation may be a longer process then previously realized. In addition, the type or extent of maturation possible may be influenced by EB size, with larger EBs capable of more extensive remodeling as revealed by multicystic morphology and initiation of early tube formation pathways while retaining pluripotency status. We anticipate that this information will be broadly useful to the stem cell and bioengineering communities in optimization of tissue engineering with pluripotent stem cells and understanding sources of variation. mRNA profiles by RNA-seq from embryoid bodies generated by different methods

Project description:Ets2-null ES cells are defective in differentiating into cardiac myocytes, evidenced by the lack of spontaneous beating, cardiac transcription factors and structural proteins. With the Phalanx mouse Onearray v2, we compared the gene expression profiles of cells derived from Ets2-null and wildtype ES cells. Standard embryoid body culture protocol was used to induce differentiation of murine ES cells. On the 10th day, replicates of either Ets2-null or control wildtype EB culture were collected in Trizol for total RNA extraction. Microarray was preformed by Phalanx.

Project description:Human embryonic stem cell-reporter line hESC-NKX2.5(eGFP/w) were differentiated to cardiomyocytes (CMs) by utilizing the spin embryoid body method. During differentiation the cells were treated with DMSO or retinoic acid (RA) from day 4-7. At day 31, cells were sorted based on GFP prior to RNA isolation. The results of this microarray demonstrate that CMs treated with RA during differentiation exhibit atrial-like gene expression profile, while DMSO-treated cells show ventricular-like gene profile.

Project description:We have recently described sustained clinical recovery associated with dampened neuroinflammation and remyelination following transplantation of neural precursor cells (NPCs) derived from human embryonic stem cells (hESCs) in a viral model of the human demyelinating disease multiple sclerosis. In order to test the general applicability of NPC transplantation, we developed a new method for the differentiation and purification of NPCs from pluripotent stem cells (PSCs). Herein, we investigated the therapeutic potential of NPCs generated from human induced pluripotent stem cells (iPSCs) in mice infected with the neurotropic JHM strain of mouse hepatitis virus (JHMV) that induces an immune-mediated demyelinating disease sharing clinical and histologic similarities to the human demyelinating disease multiple sclerosis (MS). JHMV-infected mice intraspinally transplanted with EB (embryoid body)-derived NPCs (EB-NPCs) exhibited decreased accumulation of CD4+ T cells in the central nervous system that was concomitant with reduced demyelination at the site of injection. Dampened neuroinflammation and remyelination was correlated with a transient increase in CD4+FOXP3+ regulatory T cells (Tregs) concentrated within the peripheral lymphatics. Importantly, pathological improvements were limited in comparison to our previous report on hESC-derived NPCs and did not result in significant clinical recovery. Further examination of EB-NPCs by whole genome expression analysis showed them to be significantly different than our previously published cells. These findings highlight an intrinsic disparity in the therapeutic potential of NPCs generated from pluripotent stem cells. Pluripotent stem cells were differentiated to neural precursor cells (NPCs) by two separate methods to study the differences in final cell type. The first method was a 4 factor 9 day directed differentiation. This was applied to WA09 embryonic stem cells (ESCs) as well as two lines of induced pluripotent stem cells (iPSCs) that were developed in our lab HDF51iPSC and HDF69iPSC. The other method was a multistep process that included transition through an embryoid body (EB) stage. This was done with the used on the HDF51iPCS line. For controls we used the original pluripotent stem cell lines (WA09, HDF51iPSC and HDF69iPSC) as well as HDF417 which is a human dermal fibroblast line collected by our lab.
