Data for Solid phase capture and profiling of open chromatin by spatial ATAC

Here we introduce spatial ATAC, a method that integrates transposase-accessible chromatin profiling in tissue sections with barcoded solid-phase capture to perform spatially resolved epigenomics. We show that spatial ATAC enables the discovery of the regulatory programs underlying spatial gene expression during mouse organogenesis, lineage differentiation and in human pathology.

Dataset description The dataset includes spatially-resolved chromatin accessibility profiling performed on three fresh-frozen tissue sections of HER2+ breast cancer. We provide raw data in the form of fastq files, along with processed feature barcode matrices, metadata, and photomicrographs of the tissue slices. Additionally the dataset contains spatially-resolved gene expression profiling of tissue sections from the same specimen.
