A single-cell transcriptomic map of the human and mouse pancreas reveals inter- and intra-cell population structure

Project description:While the function of the mammalian pancreas hinges on complex interactions of distinct cell types, gene expression profiles have primarily been described with bulk mixtures of cells. Here, we invoked inDrop, a droplet-based single-cell RNA-Seq method, to determine the transcriptomes of over 12,000 individual pancreatic cells from four human donors and two strains of mice. Cells could be divided into 15 clusters that matched previously characterized cell types: all endocrine cell types, including rare ghrelin-expressing epsilon-cells, exocrine cell types, vascular cells, Schwann cells, quiescent and activated pancreatic stellate cells, and four types of immune cells. We detected subpopulations of ductal cells with distinct expression profiles, and validated their existence with immuno-histochemistry stains. Moreover, among human beta-cells, we detected heterogeneity in the regulation of genes relating to functional maturation and levels of ER-stress. Finally, we deconvolve bulk gene expression samples using single-cell RNA-Seq to detect disease associated differential expression. Thus, our cross-species dataset provides a resource for the discovery of novel cell type-specific and cell type-restricted transcription factors, signaling receptors, and medically-relevant genes.

A Single-Cell Transcriptomic Map of the Human and Mouse Pancreas Reveals Inter- and Intra-cell Population Structure.

SIGNAL-seq: Multimodal Single-cell Inter- and Intra-cellular Signalling Analysis

Project description:We present SIGNAL-seq (Split-pool Indexing siGNalling AnaLysis by sequencing): a multiplexed split-pool combinatorial barcoding method that simultaneously measures RNA and post-translational modifications (PTMs) in fixed single cells from 3D models. SIGNAL-seq PTM measurements are equivalent to mass cytometry and RNA gene detection is analogous to split-pool barcoding scRNA-seq. By measuring both mRNA ligand-receptor pairs and PTMs in single cells, SIGNAL-seq can simultaneously un- cover inter- and intra-cellular regulation of tumour microenvironment plasticity. This SuperSeries is composed of the SubSeries listed below.

Spatial tissue proteomics quantifies inter- and intra-tumor heterogeneity in hepatocellular carcinoma

Project description:The inter-patient variability of tumor proteomes has been investigated on a large scale but many tumors display also intra-tumoral heterogeneity (ITH) regarding morphological and genetic features. To what extent the local proteome of tumors intrinsically differs remains largely unknown. Here, we used hepatocellular carcinoma (HCC) as a model system, to quantify both inter- and intra-tumor heterogeneity across human patient specimens with spatial resolution. We first defined proteomic features that robustly distinguish neoplastic from the directly adjacent non-neoplastic tissue by integrating proteomic data from human patient samples and genetically defined mouse models with available gene expression data. We then demonstrated the existence of intra-tumoral variations in protein abundance that re-occur across different patient samples, and affect clinically relevant proteins, even in the absence of obvious morphological differences or genetic alterations. Our work demonstrates the suitability and the benefits of using mass spectrometry based proteomics to analyze diagnostic tumor specimens with spatial resolution
