Expression of synaptic function genes in iPSC-derived induced human neurons

ABSTRACT: To determine expression levels of neuron-associated genes in induced human neurons, cultures of Ngn2-induced neurons grown on mouse glia were dissociated and assayed for nuclear RNA using the 10X Multiome kits. Associated ATAC data were not evaluated in this study. A mixture of 10 iPSC cell lines, 6 from diagnosed participants with alcohol use disorder (AUD) and 4 unaffected controls, were infected with lentiviral vectors expressing doxycycline-inducible Ngn2. Following drug selection for successful transduction, cells were plated onto primary mouse glial cells and allowed to mature for approximately 4 weeks. Cells were harvested with Accutase and Papain, then processed using standard 10X Genomics protocols using the Multiome kit. After importing into Seurat and clustering, excitatory neuron cells were selected and deconvolved to identify the source participant by matching SNPs from earlier GWAS studies. Tables of genes x barcode were then aggregated into genes x cell line matrices, which were loaded into DESeq2 for scaling and normalization. For this study, only processed data from 3 unaffected control subjects are reported. Results demonstrate robust expression of a series of synaptic receptor, channel, and associated signaling genes.

Ngn2 induces diverse neuronal lineages from human pluripotency

Project description:Human neurons engineered from induced pluripotent stem cells (iPSCs) through Neurogenin 2 (Ngn2) overexpression are widely used to study neuronal differentiation mechanisms and to model neurological diseases. However, the differentiation paths and heterogeneity of emerged neurons have not been fully explored. Here we used single-cell transcriptomics to dissect the cell states that emerge during Ngn2 overexpression across a time course from pluripotency to neuron functional maturation. We find a substantial molecular heterogeneity in the neuron types generated, with at least two populations that express genes associated with neurons of the peripheral nervous system. Neuron heterogeneity is observed across multiple iPSC clones and lines from different individuals. We find that neuron fate acquisition is sensitive to Ngn2 expression level and the duration of Ngn2 forced expression. Our data reveals that Ngn2 dosage can regulate neuron fate acquisition, and that Ngn2-iN heterogeneity can confound results that are sensitive to neuron type.

A Human Fetal Cochlear Cell Atlas Reveals a Regulatory Blueprint for Spatial Patterning - sn-Multiome

Project description:Single-nucleus multiomic data was generated from human fetal cochleae across 11, 14, and 16 post-conceptual weeks (PCW) using the 10X Genomics Chromium Next GEM Single Cell Multiome ATAC+ Gene Expression platform. Snap-frozen tissues were minced and lysed in ice-cold Nuclei Lysis Buffer, followed by filtration through a 40 μm strainer and centrifugation. Nuclear integrity was confirmed via trypan blue staining prior to mild permeabilization using 0.1× Lysis Buffer. After quenching and washing, nuclei were resuspended in Diluted Nuclei Buffer and concentration was adjusted to 4,000–8,000 nuclei/μL. Libraries were prepared following the standard 10X Multiome protocol for simultaneous gene expression and chromatin accessibility profiling. Sequencing was performed on the Illumina platform, producing paired-end reads. Raw data were processed through the Cell Ranger ARC pipeline (v2.0.0) with alignment to the GRCh38 human genome. The final output comprises paired gene expression matrices and chromatin accessibility peaks, both linked to the same individual nuclei through shared barcodes.

Single-nucleus multiome ATAC-seq and RNA-seq analysis of GCM1 knockout in rotational human tropholast organoids

Project description:Single nuclei were isolated from organoids to investigate the effects of GCM1 knockout and AAVS1 knockout (as control) on chromatin accessibility and gene expression profiles. Approximately 10,000 nuclei per sample were processed using 10x Genomics Chromium Next GEM Single Cell Multiome ATAC + Gene Expression kit, enabling simultaneous profiling of chromatin accessibility and gene expression from individual nuclei. Raw sequencing data were processed using Cell Ranger ARC to generate filtered feature-barcode matrices. Data analysis was performed in R (v4.3+) using Seurat (v4) and Signac packages.

Microarray analyses of lymph node dendritic cells (DCs) stimulated in vitro with papain or LPS

Project description:T helper type 2 (Th2) responses are induced by protease allergens and helminthes. However the molecular mechanisms that initiate Th2 responses are poorly understood. To obtain insight into this mechanism, we performed a microarray analysis of lymph node DCs stimulated in vitro with the protease allergen papain, or with LPS, a Th1 inducing stimulus. Key words: Th2 response, LPS, dendritic cells, Papain CD11c+ DCs were isolated from the lymph nodes of C57BL/6 mice, and cultured in vitro (1x106 DCs per ml) with 500 3T3-CD40L fibroblasts, either alone, or in the presence of papain (25 µg/ml) or LPS (1 µg/ml). 4h and 17h later, the cells were harvested and RNA isolated and processed for microarray analyses. RNA was extracted and processed from freshly isolated LN DCs. For a given time point, the expression profile of DCs treated with papain or LPS, were compared to that of untreated DCs
