Project description:Small vesicles, known as exosomes, are secreted from various cell types. Exosomes secreted by mesenchymal stem cells have therapeutic effects against a variety of diseases, and may be able to partially replace stem cell therapies. Previously, we established and characterized human leukocyte antigen (HLA) haplotype homo (HHH) dental pulp cell (DPC) lines from human wisdom teeth. In this report, we purified the exosomes secreted from HHH-DPCs and evaluated their therapeutic potential in a periodontitis model. The exosomes purified from HHH-DPCs showed homogeneous and spherical membrane structures, and showed low but significant expression of HLA class I molecules. The exosomes further promoted proliferation and migration in DPCs. A comparison of miRNAs revealed that the HHH-DPC exosomes contained higher levels of multiple Let-7 family miRNAs compared to HHH-induced pluripotent stem cell (iPSC)-derived exosomes. Finally, the HHH-DPC exosomes showed preventive effects in a mouse model of periodontitis induced by lipopolysaccharides (LPS). In summary, HHH-DPC exosomes expressed HLA molecules which may induce an immune response in HLA-mismatched transplantations. However, they successfully stimulated the proliferation and migration of cells and showed suppressive effects on LPS-induced periodontitis. Therefore, HHH-DPC exosomes show great potential for applications in periodontal treatments.

Project description:Single-cell RNA-seq was performed on homozygous Sox2 knockout induced pluripotent stem (iPS) cells, where residual Sox2 expression is observed from incompletely silenced retroviral transgenes. These were compared to Sox2-low iPS cells rescued by exogenous Sox2 transgenic expression, and wild-type iPS cells to assess the lineage expression profile of Sox2-low cells and degree of transcriptional heterogeneity in each population.

Project description:The Human Induced Pluripotent Stem Cells Initiative (HipSci) is generating a large, high-quality reference panel of human IPSC lines. This is a pilot submission of mass-spectrometry analyses from 18 induced pluripotent stem cell lines generated by the HipSci project. This submission includes also data for two embryonic stem cell lines, and one reference sample comprising a mixture of 42 IPSC lines.

Project description:Induced pluripotent stem cells (iPSC) are generated from somatic cells by the transgene expression of three transcription factors Oct3/4, Sox2, and Klf4 (OSK), albeit at a low efficiency. The protooncogene c-Myc enhances the efficiency of iPSC generation by OSK, but it also increases the tumorigenicity of the resulting iPSC. In the current study, we found the Gli-like transcription factor Glis1, when expressed together with OSK, to markedly enhance the generation of iPSC from both mouse and human fibroblasts. Mouse iPSC generated by OSK and Glis1 can form germline-competent chimeras. Glis1 is enriched in unfertilized oocytes and one cell-stage embryos. DNA microarray analyses revealed that Glis1 promotes multiple pro-reprogramming pathways, including Myc, Nanog, Lin28, Wnt, mesenchymal-epithelial transition (MET), and Esrrb. These results therefore demonstrated that oocyte transcription factor Glis1 effectively promote direct reprogramming during iPSC generation. Adult human fibroblasts were transduced with OSKM and OSK+Glis1 and were used for microarray analyses.

Project description:Induction of germline-competent pluripotent stem cells from mouse fibroblasts has been achieved by the ectopic expression of four genes (Oct3/4, Sox2, c-Myc and Klf4). If this method can be applied to humans for the generation of personalized human pluripotent stem cells, it would greatly facilitate the therapeutic application of stem cells by avoiding the problem of immune rejection by the recipient associated with allograft transplants. Here we show that the ectopic expression of the same four genes in human neonatal skin derived cells is sufficient to induce pluripotent stem cells indistinguishable from human embryonic stem cells in morphology, gene expression, DNA methylation, teratoma formation and long term self-renewal ability. Extensive analysis of colonies generated by ectopic expression of these four genes indicates the presence of considerable heterogeneity in the induced colonies. These results provide a new finding to generate human induced pluripotent stem cells from postnatal somatic tissues. Keywords: Cell type comparison
