Project description:We compared transcriptome of different types of NK cells including obtained from Umbilical Blood (UCB-NK) from 3 donors, both UCB56 NK cells that were isolated from the UCB unit as well as UCB34 NK cells that were differentiated from CD34+ cells, and derived from human iPSC (iPSC-NK), pre and post antigen presenting cell expansion. When comparing the similarity of the NK cells populations by the number of differentially expressed genes to iPSC NK cells, there were the pre and post expansion cells clustered together

Project description:Background: Following spinal cord injury (SCI), the inflammatory storm initiated by microglia/macrophages poses a significant impediment to the recovery process. Exosomes play a crucial role in the transport of miRNAs, facilitating essential cellular communication through the transfer of genetic material. However, the miRNAs from iPSC-NSCs-Exos and their potential mechanisms leading to repair after SCI remain unclear. This study aims to explore the role of iPSC-NSCs-Exos in microglia/macrophage pyroptosis and reveal their potential mechanisms. Methods: iPSC-NSCs-Exos were characterized and identified using transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA), and Western blot. A mouse SCI model and a series of in vivo and in vitro experiments were conducted to investigate the therapeutic effects of iPSC-NSCs-Exos. Subsequently, miRNA microarray analysis and rescue experiments were performed to confirm the role of miRNAs in iPSC-NSCs-Exos in SCI. Mechanistic studies were carried out using Western blot, luciferase activity assays, and RNA-ChIP. Results: Our findings revealed that iPSC-NSCs-derived exosomes inhibited microglia/macrophage pyroptosis at 7 days post-SCI, maintaining myelin integrity and promoting axonal growth, ultimately improving mice motor function. The miRNA microarray showed let-7b-5p to be highly enriched in iPSC-NSCs-Exos, and LRIG3 was identified as the target gene of let-7b-5p. Through a series of rescue experiments, we uncovered the connection between iPSC-NSCs and microglia/macrophages, revealing a novel target for treating SCI. Conclusion: In conclusion, we discovered that iPSC-NSCs-derived exosomes can package and deliver let-7b-5p, regulating the expression of LRIG3 to ameliorate microglia/macrophage pyroptosis and enhance motor function in mice after SCI. This highlights the potential of combined therapy with iPSC-NSCs-Exos and let-7b-5p in promoting functional recovery and limiting inflammation following SCI.

Project description:Human iPSCs were differentiated towards an induced-SMC (iSMC) phenotype in a 10-day protocol. Proteomics was performed throughout the entire differentiation time course to provide a robust, well-defined starting and ending cell population. Proteomics data verified iPSC differentiation to iSMCs. Proteomics comparison with primary human SMCs showed a high correlation with iSMCs. After iSMC differentiation, we initiated calcification in the iSMCs by culturing the cells in osteogenic media for 17 days.

Project description:We differentiated mouse Col2.3 GFP ESCs and iPSCs to osteoblast progenitors and confirmed the osteoblast identity of ESC- and iPSC-derived osteoblasts using RNA-sequencing and hierarchical clustering, and demonstrate that Col2.3GFP+ sorted cells are more similar to freshly isolated Col2.3GFP+ osteoblasts from mouse bone than to unsorted cells based on whole genome expression profiling.

Project description:The differentiation of human induced pluripotent stem cells (iPSCs) into macrophages is a complex process involving the emergence of diverse cell types and progenitors. In this study, we conducted a comprehensive single-cell transcriptomic analysis to elucidate the dynamics of iPSC-to-macrophage differentiation and explore the heterogeneity of arising cell populations. Two different cytokine conditions were employed to modulate differentiation, and we hypothesized that these conditions would yield distinct cell compartments. Our results reveal a nuanced cellular trajectory from iPSCs to macrophages, uncovering key intermediates and transitional states. Notably, the emerging cell populations remain consistent, albeit with variations in their proportions, with IL-3-only condition exhibiting a lower proportion of mature cells. This investigation advances our understanding of iPSC-to-macrophage differentiation, shedding light on the cellular heterogeneity and trajectory dynamics. The findings have implications for the development of targeted differentiation strategies and the exploration of novel therapeutic applications in regenerative medicine and immunology.

Project description:Induced pluripotent stem cells (iPSCs) are an essential tool for studying cellular differentiation and cell types that are otherwise difficult to access. We investigated the use of iPSCs and iPSC-derived cells to study the impact of genetic variation on gene regulation across different cell types and as models for studies of complex disease. To do so, we established a panel of iPSCs from 58 well-studied Yoruba lymphoblastoid cell lines (LCLs); 14 of these lines were further differentiated into cardiomyocytes. We characterized regulatory variation across individuals and cell types by measuring gene expression levels, chromatin accessibility and DNA methylation. Our analysis focused on a comparison of inter-individual regulatory variation across cell types. While most cell type-specific regulatory quantitative trait loci (QTLs) lie in chromatin that is open only in the affected cell types, we found that 20% of cell type-specific regulatory QTLs are in shared open chromatin. This observation motivated us to develop a deep neural network to predict open chromatin regions from DNA sequence alone. Using this approach, we were able to use the sequences of segregating haplotypes to predict the effects of common SNPs on cell type-specific chromatin accessibility.

Project description:Retinitis pigmentosa (RP) is an irreversible and inherited retinopathy. RPGR mutations are the most common causes of this disease. It remains challenging to decipher the mechanism of RPGR mutation because of the lack of appropriate study models. The substitution of patient-specific diseased retina without ethical restrictions is desired and iPSC-derived 3D retina is the best choice. In our experiment, we generated iPSCs from one RP patient with 2-bp frameshift mutation in the exon14 of RPGR gene, which were differentiated into retinal organoids. Also we generated iPSCs from a normal control and differentiated those control-iPSCs into healthy retinal organoids. Samples of patient- and control-retinal organoids at W0, W7, W13 (two replicates), W18 (two replicates) and W22 (two replicates for patient) were collected for RNA-seq. Corrected-iPSC were derived from CRISPR/Cas9-mediated gene correction. Then we collected the corrected-iPSC derived retinal organoids at W0, W7, W13 (two replicates), W18 (two replicates) and W22 (two replicates) for RNA-seq. Through the RNA-seq data, we demonstrate that patient-specific iPSC-dervied 3D retinae can recapitulate disease progress of Retinitis Pigmentosa through presenting defects in photoreceptors' gene profile. CRISPR/Cas9-mediated gene correction can rescue photoreceptor gene profile. Those transcriptome are consistent with the phenotype and function.
