mRNAseq of Huntington's disease and control patient iPSC-derived neural cells

Project description:Purpose: The goals of this study are to compare the transcriptomic profile (mRNA-seq) of HD and control patient iPSC-derived neural cells to identify alterations in gene expression Methods: RNA were isolated from HD and control iPSC-derived neural cells. mRNAseq using Illumina Truseq mRNA PolyA+ v2 lib prep and Hiseq 2000. Statistical difference in mRNA levels were calculated with subsequent GO and pathway analysis Results: mRNAseq and statistical analysis revealed 1869 differentially expressed genes between HD and control iPSC-derived neural cells. Conclusions: Our study shows 1869 differentially expressed genes between HD and control iPSC-derived neural cells, and reveals gene networks that relevant to the mechanism of HD pathogenesis.

Differentially expressed (DE) genes analysis in synovial fluid mesenchymal stem cells (SF-MSCs), SF-MSC derived iPSCs and iPSC derived MSCs (iPSC-MSCs)

Project description:We report the application of next-generation sequencing (NGS) to analysis the gene expression profile among three different cells:SF-MSCs, iPSCs and iPSC-MSCs. Our results shown that iPSC-MSCs were more similar to SF-MSCs than iPSCs.

Comparison of human isogeneic Wharton’s Jelly MSCs and iPSC-derived MSCs responses to interferon-gamma (IFNG) stimulation

Project description:To explore differences between native MSCs (nMSCs) and iPSC-derived MSCs (iMSCs), we developed isogeneic lines from Wharton’s Jelly (WJ) from the umbilical cords of two donors (#12 and #13) under xeno-free conditions. Next, we reprogrammed them into iPSCs (iPSC12 and iPSC13) and subsequently differentiated them back into iMSCs (iMSC12 and iMSC13) using two different protocols, which we named ARG and TEX. As an additional control, we used human embryonic stem cell line KCL034 to differentiate the cells into eMSC following ARG and TEX protocols. We assessed IFNG-induced changes in all lines. Our data suggest that, following a careful selection and screening of donors, nMSCs from umbilical’s cord WJ can be easily reprogrammed into iPSCs providing an unlimited source of material for differentiation into iMSCs. However, the differentiation protocol should be chosen depending on their clinical use.

Modeling Familial Cancer with iPSC Approaches

Project description:In vitro modeling of human disease has recently become feasible with the adoption of induced pluripotent stem cell (iPSC) technology. Here, we established patient-derived iPSCs from an Li-Fraumeni Syndrome (LFS) family and investigated the role of mutant p53 in the development of osteosarcoma (OS). Several members of this family carried a heterozygous p53(G245D) mutation and presented with a broad spectrum of tumors including OS. Osteoblasts (OBs) differentiated from iPSC-derived mesenchymal stem cells (MSCs) recapitulated OS features including defective osteoblastic differentiation (OB differentiation) as well as tumorigenic ability. Systematic analyses revealed that the expression of genes enriched in LFS-derived OBs strongly correlated with decreased time to tumor recurrence and poor patient survival. In silico cytogenetic region enrichment analysis (CREA) demonstrated that LFS-derived OBs do not have genomic rearrangements and hence are a particularly valuable tool for elucidating early oncogenic events prior to the accumulation of secondary alterations. LFS OBs exhibited impaired upregulation of the imprinted gene H19 during osteogenesis. Restoration of H19 expression in LFS OBs facilitated osteogenic differentiation and repressed tumorigenic potential. By integrating human imprinted gene network (IGN) and functional genomic analyses, we found that H19-mediates suppression of LFS-associated OS through the IGN component DECORIN (DCN). Downregulation of DCN impairs H19-mediated osteogenic differentiation and tumor suppression. In summary, these findings demonstrate the feasibility of studying inherited human cancer syndromes with iPSCs and also provide molecular insights into the role of the IGN in p53 mutation-mediated tumorigenesis. mRNAseq profiling during mesenchymal stem cell differentiation to osteoblasts.
