Clustering-independent estimation of cell abundances in bulk tissues using single-cell RNA-seq data
<p>ConDecon is a clustering-independent method for inferring the likelihood for each cell in a single-cell dataset to be present in a bulk tissue. This repository contains the raw data of the benchmarking analyses presented in the original publication using the pipeline of Avila-Cobos et al. (10.1038/s41467-020-19015-1). We used this pipeline to evaluate the ability of ConDecon and 17 other deconvolution methods to infer discrete cell type abundances in bulk tissues. The compressed file in this repository contains the synthetic bulk data, ground truth cell type proportions, and the predicted cell type proportions for each method and dataset associated with these analyses. Additional details can be found in the Methods section of the ConDecon publication.</p>

A method to investigate Pathological Variant load of Mitochondrial DNA in single human Mesenchyma stem cells
<p>Mesenchymal stem cells (MSCs) are the parent cells to many cells of the musculoskeletal system including osteoblasts. Previous work has shown that in mouse models mitochondrial DNA (mtDNA) pathological variants lead to dysfunction of the respiratory chain of these osteoblasts and the premature development of age related osteoporosis. An increased rate of respiratory chain deficiency has also been observed in human osteoblasts. mtDNA mutates at an enhanced rate compared to nuclear DNA and has been linked to the ageing process in humans. </p> <p>We have developed and optimised an experimental pipeline to isolate single MSCs using flow cytometry before performing next generation sequencing to analyse the pathogenic variant load of 13 patients aged 22-88 to assess if pathogenic variants exist in mesenchymal stem cells and if there are age related changes.</p> <p>Across all patients and all cells mtDNA pathological variants were present at similarly low levels. As per previous studies we found increased pathogenic variants within the mtDNA control region (D-Loop). However overall, there was no significant difference in the distribution of variants across the rest of the genome in all patients. Although a higher proportion of non-synonymous variants were seen this was not statistically significant.</p> <p>We have shown that it is possible to isolate and sequence individual MSCs and observe mtDNA pathological variants. This gives a snapshot in time of the variant load for each patient. Due to low sample numbers compared to other studies investigate mtDNA in other cell types, we did not observe any age related increase in pathological variants. However this adds further evidence that clonally expanded, somatic mtDNA variants are common and could contribute to age related disease including osteoporosis.</p>

Comprehensive single-cell atlas of the mouse retina
<p><strong>Abstract:</strong></p> <p>Single-cell RNA sequencing (scRNA-seq) has advanced our understanding of cellular heterogeneity at the single-cell resolution by classifying and characterizing cell types in multiple tissues and species. While several mouse retinal scRNA-seq reference datasets have been published, each dataset either has a relatively small number of cells or is focused on specific cell classes, and thus is suboptimal for assessing gene expression patterns across all retina types at the same time. To establish a unified and comprehensive reference for the mouse retina, we first generated the largest retinal scRNA-seq dataset to date, comprising approximately 190,000 single cells from C57BL/6J mouse whole retinas. This dataset was generated through the targeted enrichment of rare population cells via antibody-based magnetic cell sorting. By integrating this new dataset with public datasets, we conducted an integrated analysis to construct the Mouse Retina Cell Atlas (MRCA) for wild-type mice, which encompasses over 330,000 single cells. The MRCA characterizes 12 major classes and 138 cell types. It captured consensus cell type characterization from public datasets and identified additional new cell types. To facilitate the public use of the MRCA, we have deposited it in CELLxGENE, UCSC Cell Browser, and the Broad Single Cell Portal for visualization and gene expression exploration. The comprehensive MRCA serves as an easy-to-use, one-stop data resource for the mouse retina communities.</p> <p> </p> <p><strong>Data description:</strong></p> <p>1.
