Single cell sequencing of endoscopic biopsies from Barrett's oesophagus and proximal tissue from the normal GI tract

Barrett’s oesophagus is a precursor of oesophageal adenocarcinoma. In this common condition, squamous epithelium in the oesophagus is replaced by columnar epithelium in response to acid reflux. Barrett’s oesophagus is highly heterogeneous and its relationships to normal tissues are unclear. We investigated the cellular complexity of Barrett’s oesophagus and the upper gastrointestinal tract using RNA-sequencing of single cells from multiple biopsies from six patients with Barrett’s oesophagus and two patients without oesophageal pathology.

EGAD00001004344	Data consists of 4,640 RNA-sequencing sample libraries. These libraries were sequenced from four sites of the upper gastro-intestinal tract (Barrett’s oesophagus, proximal normal oesophagus, proximal normal stomach, and duodenum) in two experiments. 4,587 libraries were produced in the first experiment in which whole transcriptomes were isolated single cells dissociated from endoscopic biopsy tissue obtained from the four previously mentioned tissues. The other 53 libraries were produced in the second experiment in which whole transcriptomes were isolated from whole tissue from endoscopic biopsies of the four previously mentioned tissues. The data found here are stored in the raw fastq file format from paired end sequencing.	Illumina HiSeq 4000	4640
