Single-cell analyses define a continuum of cell state and composition changes in the malignant transformation of polyps to colorectal cancer

Mapping molecular changes across malignant transformation We generated single-cell data for 81 samples collected from eight FAP and seven non-FAP donors (Fig. 1a and Supplementary Tables 1 and 2). For each tissue, we performed matched scATAC-seq and snRNA-seq (10x Genomics). We obtained high-quality single-cell chromatin accessibility profiles for 447,829 cells…

GeneActivity without Fragments file in Seurat for Integrating scRNA-seq and scATAC-seq

Hi all, I am new to R and Seurat, and I am following Seurat tutorials to find anchors between RNA-seq and ATAC-seq data according to: Combining the two tutorials is difficult for a cell line data set I am using for SNARE-seq Human here. I managed to run the following…

Database for scATAC-seq datasets similar to ENCODE? : bioinformatics

Does anyone know of any public scATAC-seq databases? Up until now I’ve been using the scATAC.Explorer library in R to get my scATAC datasets, but there doesn’t seem to be a fragment file associated with any of the experiments. I’d like to plot some gene activity matrices/coverage plots. Alternatively, if…

HyDrop: droplet-based scATAC-seq and scRNA-seq using dissolvable hydrogel beads

Reviewer #1 (Public Review): Droplet-based single-cell method development has stalled in the past years. The field has been overtaken by commercial solutions that optimized performance, but at much higher costs and without any possibility for customization. More recently, combinatorial indexing methods (e.g. SPLIT-seq) have gained popularity, requiring no specialized equipment…

BAMboozle removes genetic variation from human sequence data for open data sharing

Strategy for stripping human sequence data of genetic information To lower the barriers in sharing sequence data, we propose, like others recently17, to remove information on genetic variation that could be used to infer the identity from aligned reads and compromises the privacy of the donor (Fig. 1a). Genetic variation, including…

Comparative cellular analysis of motor cortex in human, marmoset and mouse

Statistics and reproducibility For multiplex fluorescent in situ hybridization (FISH) and immunofluorescence staining experiments, each ISH probe combination was repeated with similar results on at least two separate individuals per species, and on at least two sections per individual. The experiments were not randomized and the investigators were not blinded…
