Project description:A growing body of single-cell multi-omic tools enables a better understanding of gene regulation underlying development and disease. Tools mapping chromatin and gene expression (such as SHARE-seq) are limited in sensitivity and scalability. Here, we describe SHARE-seqV2 and its associated cloud-computing resource, enabling single-cell analysis at improved quality, robustness, and scale. We apply SHARE-seqV2 across various cell lines, primary tissues, and immune cells, demonstrating a generalizable platform for single-cell multi-omics.

Project description:Formation of the blood from self-renewing hematopoietic stem cells to terminal lineages necessarily involves epigenomic modifications of the genome to control regulator and signature gene expression. By analysing the global expression profiles of hematopoietic stem cells (HSCs), in vivo differentiated CD4+ T cells and CD19+ B cells as well as in vitro differentiated erythrocyte precursor cells, we identified hundreds of transcripts showing type-specific expression in these cell types. To understand the epigenomic changes related to tissue-specific expression during HSC differentiation, we examined the genome-wide distribution of H3K4me1, H3K4me3, H3K27me1, H3K27me3, histone variant H2A.Z, chromatin remodeler BRG1, and RNA Polymerase II in the same four cell types, as well as embryonic stem cells. Analysis of these datasets revealed that numerous key differentiation genes are primed for expression by Brg1 and Pol II binding, as well as bivalent modifications in the HSCs prior to their expression in downstream differentiated cell types. Much of this bivalency in HSC is retained from embryonic stem cells. After differentiation, these modified regions resolve to active chromatin modification configuration in the specific lineage, while in parallel differentiated lineages the bivalent modification remains; Pol II and Brg1 are lost in closer lineages but bivalency resolves to silent monovalency in more distant lineages. Correlation of tissue-specific gene expression with the epigenomic changes predicts tens of thousands of potential common enhancers and tissue-specific enhancers, which may critically contribute to the expression patterns. We provide a valuable dataset for further understanding the regulatory mechanisms of differentiation and function of blood lineages. This SuperSeries is composed of the SubSeries listed below.

RNA-Seq: This submission comprises RNA-Seq profiling of in vivo differentiated human B cells and hematopoietic stem cells. Re-analyzed data for three cell types: The HSCs were previously uploaded as GSM651554 (SRX037948), but processed differently for this upload. The erythrocyte precursors and T cells have also been previously uploaded as GSM651555 (SRX037949) and GSM406414 (SRX005317), respectively. They were treated as in GSM651554, but processed as here. The processed files generated by our re-analysis are linked below as supplementary files.

Project description:We developed an optimized, low-cost, split-pool barcoding-based multimodal profiling protocol based upon SHARE-seq (concurrent single-cell ATAC/RNA-seq). With SHARE-seq, we profiled human kidney samples from multiple different anatomical regions. Therefore, we develop a large-scale multimodal single-cell atlas for 3D anatomy of the human kidney.
