Project description:The utility of human pluripotent stem cells as a tool for understanding disease and as a renewable source of cells for transplantation therapies is dependent on efficient differentiation protocols that convert these cells into relevant adult cell types. Here we report the robust and efficient differentiation of human pluripotent stem cells into adipocytes. We found that inducible expression of PPARG2 in pluripotent stem cell-derived mesenchymal progenitor cells programmed their development towards an adipocyte cell fate. Using this approach, multiple human pluripotent cell lines were differentiated into adipocytes with efficiencies of 85% to 90%. These pluripotent stem cell-derived adipocytes retained their identity independent of transgene expression, could be maintained in culture for several weeks, expressed mature markers, and exhibited mature functional properties such as lipid catabolism in response to a beta-adrenergic stimulus. Global transcriptional and lipid metabolomic analyses further confirmed the identity and maturity of these pluripotent stem cell-derived adipocytes.

Global transcriptional and lipid metabolomic analyses further confirmed the identity and maturity of these pluripotent stem cell-derived adipocytes. Mesenchymal progenitor cells (MPCs) derived from human embryonic stem cells hESCs and induced pluripotent stem cells (iPSCs) along with adipose-derived stromal vascular cells (ADSVCs) were subjected to induction of PPAR2 and compared to primary fat samples. Overall 2 ADSVC (ADSVC 24 nd 49) lines, 1 hESC (HUES9) line and 1 iPSC (BJRiPS) line were differentiated into MPCs, PPAR2 programmed, and compared to untreated MPCs and primary fat samples from 2 individuals. Each condition is either represented in duplicate or triplicate and there are two universal reference spots to aid in slide-dependant batch effects (24 samples total). Supplementary file(s): GeneSymbol-collapsed data represent the final normalized data used for analyses in the manuscript.

Each condition is either represented in duplicate or triplicate on affymetrix HuGene-1_0-st arrays. MPCs derived from the hESC lines HUES2 and HUES8, ADSVCs, and BJRiPS were also run on a separate platform (HG-U133_Plus_2) with more GEO presence to facilitate analysis (34 samples, two platforms total).

Project description:Despite the progress in safety and efficacy of cell therapy with pluripotent stem cells (PSCs), the presence of residual undifferentiated stem cells or proliferating neural progenitor cells (NPCs) with rostral identity has remained a major challenge. Here we reported the generation of an LMX1A knock-in GFP reporter human embryonic stem cell (hESC) line that marks the early dopaminergic progenitors during neural differentiation. Purified GFP positive cells in vitro exhibited expression of mRNA and proteins that characterized and matched the midbrain dopaminergic identity. Further proteomic analysis of enriched LMX1A+ cells identified several membrane associated proteins including CNTN2, enabling prospective isolation of LMX1A+ progenitor cells. Transplantation of hPSC-derived purified CNTN2+ progenitors enhanced dopamine release from transplanted cells in the host brain and alleviated Parkinson’s disease symptoms in animal models. Our study establishes an efficient approach for purification of large numbers of hPSC-derived dopaminergic progenitors for therapeutic applications.

Project description:We explored the hypothesis that adipose tissue contains epigenetically distinct subpopulations of adipocytes that are differentially potentiated to record cellular memories of their environment. Adipocytes are large, fragile, and technically difficult to efficiently isolate and fractionate. We developed fluorescence nuclear cytometry (FNC) and fluorescence activated nuclear sorting (FANS) of cellular nuclei from Sus scrofa visceral adipose tissue (SsVAT) using the levels of the pan-adipocyte protein, peroxisome proliferator-activated receptor gamma-2 (PPARg2) to distinguish PPARg2-Positive nuclei from PPARg2-Neg (negative) leukocyte, endothelial, and adipocyte progenitor cell nuclei. PPARg2-Postive VAT nuclei showed 2- to 50-fold higher levels of transcripts encoding most of the chromatin-remodeling factors assayed regulating the methylation of histones and DNA cytosine (e.g., DNMT1, DNMT3A, TET2, TET3, KMT2C, SETDB1, PAXP1, ARID1A, KMT2C, JMJD6, CARM1/PRMT4, PRMT5). PPARg2-Positive nuclei have a large decondensed chromatin structure. TAB-seq demonstrated 5´-hydroxymethylcytosine (5hmC) levels were remarkably dynamic in the gene body of PPARg2-Positive nuclei, dropping 3.8-fold from the highest quintile of expressed genes to the lowest. Sus scrofa VAT (SsVAT) nuclei were isolated from SsVAT. SsVAT nuclei were stained with PPARg2 and sorted with fluorescence activated nuclear sorting (FANS) into PPARg2-High, PPARg2-Med (Medium), PPARg2-Low, and PPARg2-Neg (Negative) four populations.TAB-seq data on 5-hydroxymehtylcytosine (Yu, M. et al. 2012. Cell 149, 1368-1380) was collected from genomic DNA isolated from PPARg2-High, PPARg2-Med+Low (pooled PPARg2-Med and PPARg2-Low), and PPARg2-Neg SsVAT nuclei.

Project description:To investigate the effect of ZNF395 on adipogenesis, we tested whether ZNF395 enhance cell conversion from human dermal Fibroblast (FIB) to Adipocyte (ADP). PPARG2 was reported as a master regulator and can induce adipogenesis in non-adipogenic fibroblasts. We transduced PPARG2 with or without ZNF395 in FIB with lentivirus. Interestingly, co-transduction of PPARG2 and ZNF395 showed higher occurrence of adipocyte-like cells as compared with PPARG2 alone. Moreover, genes related with lipid metabolic process and lipid transport was significantly up-regulated in combination of PPARG2 and ZNF395. These results suggest that ZNF395 co-ordinate the transcriptional regulatory pathway with PPARG2, necessary for the induction of adipogenesis.

Total RNA was obteined from human dermal fibroblast transduced with mock lentivirus vector (FIB_ctrl), PPARG2 (FIB_PPARG2) and co-transduced with PPARG2 and ZNF395 (FIB_PPARG2+ZNF395).

Project description:We have generated human induced Pluripotent Stem cells (hiPSc) using Sendai virus-mediated delivery of reprogramming factors. hiPSc lines have been screened using SNP array to assess chromosomal stability (alongside the fibroblast lines from which they derived), and validation of the pluripotency of the hiPSc lines is provided by Pluritest assessment of transcriptome datasets, prior to differentiation and downstream assays. Single cell RT-qPCR analysis of induced pluripotent stem cell-derived cortical neurons reveals frequent dual layer identity. Handel AE, Chintawar S, Lalic T, Whiteley E, Giustacchini A, Argoud K, Sopp P, Bowden R, Cowley SA, Newey S, Ackerman C, Ponting CP and Cader ZM. Submitted human iPSc lines were derived from human dermal fibroblasts from control donors. SNP and gene expression datasets from control lines. Note that iPS NHDF-1, also used in the current study, has been published previously [Van Wilgenburg B., Browne C., Vowles J. & Cowley S. A.
