Project description:We used snRNA-seq to investigate an entire adult mammalian heart of BL6 mice. Whole hearts were harvested from 4 male mice (12 weeks) after cervical dislocation. The hearts were pooled and nuclei isolated using the Nuclei PURE Prep isolation kit (Sigma-Aldrich, Darmstadt, Germany) according to the manufacturer’s protocol. Sequencing was conducted by Genewiz (Leipzig, Germany) on the 10xGenomics system. Single nuclei were captured in droplet emulsions and snRNA-seq libraries were constructed as per the 10x Genomics protocol using GemCode Single-Cell 3′ Gel Bead and Library V3 Kit. RNA was controlled for sufficient quality on an Agilent 2100 Bioanalyzer system and quantified using a Qubit Fluorometer.

Project description:Purpose: to depict the single-cell map and reveal the heterogeneity of hPSC derived macrophages Methods: Differentiation day 14 iMacs were dissociated to obtain a single-cell suspension. scRNA-seq and scATAC-seq library preparation and sequencing were done by CapitalBio Technology (https://www.capitalbiotech.com/). scRNA-seq, the cell suspension was immediately loaded onto the Chromium Single Cell Controller (10× Genomics) for droplet formation. cDNA and subsequent sequencing library were generated using Chromiun Single Cell 3’ Reagent Kit (v3 Chemistry) (10× Genomics) according to the instruction manual. For sc-ATAC-seq, cell nuclei were extracted with Chromiun Nuclei Isolation Kit (v2 Chemistry) (10x Genomics) and then loaded onto the Chromium Single Cell Controller for droplet formation. Results: ScRNA-seq and scATAC-seq data of differentiation day 14 iMacs from hPSCs Conclusions: day 14 differentiation culture, which consisted primarily of monocytes and macrophages.

Project description:We used snRNA-seq to investigate for the first time an entire adult mammalian heart. To avoid potential aberrations due to inbreeding, we relied on an outbred mice strain (Fzt:DU) (Dietl, G.; Langhammer, M.; Renne, U. Model simulations for genetic random drift in the outbred strain Fzt:DU. Arch. Anim. Breed. 2004, 47, 595–604). Whole hearts were harvested from 4 male mice (12 weeks) after cervical dislocation. The hearts were pooled and nuclei isolated using the Nuclei PURE Prep isolation kit (Sigma-Aldrich, Darmstadt, Germany) according to the manufacturer’s protocol. Sequencing was conducted by Genewiz (Leipzig, Germany) on the 10xGenomics system. Single nuclei were captured in droplet emulsions and snRNA-seq libraries were constructed as per the 10x Genomics protocol using GemCode Single-Cell 3′ Gel Bead and Library V3 Kit. RNA was controlled for sufficient quality on an Agilent 2100 Bioanalyzer system and quantified using a Qubit Fluorometer.

Project description:This study used droplet-based snATAC-seq to profile the chromatin accessibility landscape of 91,922 nuclei in the mouse cerebellum across eleven developmental stages, from the beginning of neurogenesis (e10.5) till adulthood (P63). The study included two biological replicates per stage, one from each sex. Cerebelli were dissected as whole or in two halves, nuclei were extracted and profiled using 10x single-cell ATAC reagent kit (v1.0) and a Chromium controller. Libraries were sequenced using paired-reads on Illumina NextSeq 550 and initial data processing was performed using Cellranger ATAC (1.1).

Project description:Archived tissues are a vast resource of annotated clinical samples. To expand their use for translational studies, we optimized flow sorting and sequencing of single nuclei from archived frozen and FFPE tumor tissues. Our methods, which include isolation and preparation of intact nuclei suitable for library preparations, quality control (QC) metrics for each step, and a single cell sequencing bioinformatic processing and analysis pipeline, were validated with flow sorted nuclei from matching frozen and FFPE ovarian cancer surgical samples and a sequencing panel of 553 amplicons targeting single nucleotide and copy number variants in genes of interest.

Project description:We develop a large-scale single-cell ATAC-seq method (txci-ATAC-seq) by combining Tn5-based pre-indexing with 10X Genomics barcoding. Leveraging this molecular hashing strategy, we demonstrate that txci-ATAC-seq enables the indexing of up to 200,000 nuclei across multiple samples in a single emulsion reaction, representing a ~22-fold increase in throughput compared to the standard workflow at the same collision rate. To improve the multiplexing capability of this new technique, we further develop a "phased" protocol variant (Phased-txci-ATAC-seq) that effectively decouples sample processing from library preparation and has the potential to profile up to 96 samples simultaneously. In this study, we profile 449,953 nuclei across diverse tissues, including the human cortex, mouse brain, human lung, mouse lung, mouse liver, and lung tissue from a club cell secretory protein knockout (CC16-/-) model. Our study of CC16-/- nuclei uncovers previously underappreciated technical artifacts derived from remnant 129 mouse strain genetic material, which cause profound cell-type-specific changes in regulatory elements near many genes, thereby confounding the interpretation of this commonly referenced mouse model.

Project description:This study used droplet-based snATAC-seq to profile the chromatin accessibility landscape of 19,204 nuclei in the opossum (Monodelphis domestical) cerebellum across two developmental stages (postnatal day 21 and adult). The study included two biological replicates per stage, one from each sex, and an additional adult sample enriched for white matter. Cerebelli were dissected in two halves, nuclei were extracted from one half and profiled using 10x single-cell ATAC reagent kit (v1.1) and a Chromium controller. The white matter enriched sample was dissected from coronal cerebellum slices. Libraries were sequenced using paired-reads on Illumina NextSeq 550 and initial data processing was performed using Cellranger ATAC (1.1).

Project description:Purpose: The goal of this study is to determine whether hepatic deletion of Wtapaffects chromatin accessibility. Methods: Each liver sample was pooled from three Wtap-HKO and Wtapflox/flox mice, respectively. Three independent biological replicates of each group were used for ATAC-seq. Nuclei was extracted from liver samples, and the nuclei pellet was resuspended in the Tn5 transposase reaction mix. The transposition reaction was incubated at 37°C for 30 min. Equimolar Adapter1 and Adatper 2 were added after transposition, PCR was then performed to amplify the library. After the PCR reaction, libraries were purified with the AMPure beads and library quality was assessed with Qubit. The clustering of the index-coded samples was performed on a cBot Cluster Generation System using TruSeq PE Cluster Kit v3-cBot-HS (Illumina) according to the manufactuer’s instructions. After cluster generation, the library preparations were sequenced on an Illumina NovaSeq 6000 platform and 150 bp paired-end reads were generated. ATAC-seq analysis was performed using a standard protocol. Results: The hepatic chromatin accessibility in Wtapflox/flox and Wtap-HKO mice were characterized.
