Project description:Gene expression study of human and Chimpanzee iPS cell. Affymetrix GeneChip Human Genome U133 Plus 2.0 Array were used to examine differentially expressed genes between human and chimpanzee iPS cells
Project description:ChIP-seq for H3K4me3 and H3K27me3 were conducted for iPS cells of human-1 (409-B2/HPS0076), human-2 (Nips-B2/HPS0223), chimpanzee-1 (kiku/0138F-1), and chimpanzee-2 (mari/0274F-2). The reads were mapped to the respective genomes (hg38 for human and panTro5 for chimpanzee).
Project description:mRNA-seq were conducted for iPS cells of human-1 (409-B2/HPS0076), human-2 (Nips-B2/HPS0223), chimpanzee-1 (kiku/0138F-1), and chimpanzee-2 (mari/0274F-2). To compare gene expression levels, the reads were first mapped to the chimpanzee genome (panTro5), and mapped reads were then mapped to the human genome (hg38). Gene expression was anlyzed based on the hg38 annotation.
Project description:Small RNA-seq were conducted for iPS cells of human-1 (409-B2/HPS0076), human-2 (Nips-B2/HPS0223), chimpanzee-1 (kiku/0138F-1), and chimpanzee-2 (mari/0274F-2). The human samples were mapped to the human genome (hg38) and the chimpanzee samples were mapped to the chimpanzee genome (panTro5). The mapped reads for individual TE copies (in the repeatmasker tables downloaded from UCSC genome browser) were counted, and those for the same subfamily were summed up. The counts were normalized by RPM (reads per million genome-mapped reads).
Project description:We compared a 5 week time course of cortical organoid differentiation across human, chimpanzee, orangutan, and rhesus using bulk RNAseq. In addition, single cell RNAseq was performed on a subset of time points from human cells in weeks 0, 1, 2, and 5.
Project description:Transcriptional profiling of human iPS-HSCs overexpressing LHX2 compared with control iPS-HSCs, which were cocultured with human induced pluripotent stem cell-derived hepatic progenitor cells (iPS-HPCs).
Project description:In the last decade, induced pluripotent stem (iPS) cells have revolutionized the utility of human in vitro models of neurological disease. The iPS-derived and differentiated cells allow researchers to study the impact of a distinct cell type in health and disease as well as performing therapeutic drug screens on a human genetic background. In particular, clinical trials for Alzheimer's disease (AD) have been failing. Two of the potential reasons are first, the species gap involved in proceeding from initial discoveries in rodent models to human studies, and second, an unsatisfying patient stratification, meaning subgrouping patients based on the disease severity due to the lack of phenotypic and genetic markers. iPS cells overcome this obstacles and will improve our understanding of disease subtypes in AD. They allow researchers conducting in depth characterization of neural cells from both familial and sporadic AD patients as well as preclinical screens on human cells. In this review, we briefly outline the status quo of iPS cell research in neurological diseases along with the general advantages and pitfalls of these models. We summarize how genome-editing techniques such as CRISPR/Cas9 will allow researchers to reduce the problem of genomic variability inherent to human studies, followed by recent iPS cell studies relevant to AD. We then focus on current techniques for the differentiation of iPS cells into neural cell types that are relevant to AD research. Finally, we discuss how the generation of three-dimensional cell culture systems will be important for understanding AD phenotypes in a complex cellular milieu, and how both two- and three-dimensional iPS cell models can provide platforms for drug discovery and translational studies into the treatment of AD.

Project description:Disease-specific induced pluripotent stem (iPS) cells have been used for a model to analyze pathogenesis of the disease. We generated iPS cells derived from a fibroblastic cell line of ataxia telangiectasia (AT-iPS cells). In analysis of AT-iPS cells, the human wild-type iPS cell line (MRC5-iPS) was generated and cultured in the same conditions as the diseased iPS cell lines. It is an ideal control cell line for the disease and patient-specific iPS cell lines. Because MRC5-iPS cells exhibited considerable chromosomal abnormalities in vitro, we performed a structural alteration analysis by using a SNP genotyping array for MRC5-iPS cell line, Tic, at passage 15, passage 30, and passage 37.
