hESCNeuroDiffParacet is an user-friendly, integrative open-source Shiny-based web app using R programming for visualization of massive single-cell chromatin accessibility data (scATAC-seq) of paracetamol exposure on human embryonic stem cells (hESCs) undergoing in vitro neuronal differentiation analyzed using on ArchR (Corces et al., 2021).
The ArchR objects saved in folders along with HDF5 formatted Arrow files are used for input in hESCNeuroDiffParacet. Here we show single-cell ATAC seq data of paracetamol exposure on human embryonic stem cells (hESCs) undergoing in vitro neuronal differentiation.
Source code for ShinyArchR.UiO is available at ShinyArchR.UiO.
For more details please visit https://Cancell.medisin.uio.no.
ShinyArchR.UiO was developed at University of Oslo.
Our latest preprint associated with this dataset on multi-omics analysis of understanding effects of paracetamol exposure on hESC undegoing in-vitro neuronal differentiation is available at Spildrejorde et al,2022
Source codes for analysis is freely available at Github Neuralparacet. For more details on scATAC seq data analysis,please refer to full manual of ArchR and Nature genetics paper.
For more details on neuronal differentiation protocol, please see our Star Protocol article
Shiny and the tidyverse, of course.
Seurat and SingleCellExperiment are used in integration of the scRNA Seq data .
