What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.
Organism
Homo sapiens (human)
Samples
10 samples: 3 × BVLO # vs 2 × LO #Groups are read from the sample names, not from the paper. Check the list below.
Data you can get
A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.

Summary (written by the submitters)
Bile duct (BD) structure is crucial for bile secretion to maintain liver homeostasis. Although several human induced pluripotent stem cell (hiPSC)-derived liver organoids have been generated, no study recapitulates the development of BD tubules. Here, we focus on an environmental cue to form tubular BDs, specifically the interaction between liver progenitors with the portal vein (PV).

We co-culture hiPSC-liver progenitors with PV-like hiPSC-blood vessel (hiPSC-BV) which consists of immature hiPSC-smooth muscle cells (SMC) with a similar character to fetal PV-SMC. After two weeks, liver progenitors within hiPSC-BV-integrated liver organoid (BVLO) differentiate into the cholangiocyte-lineage and establish tubular structures with epithelial characteristics including intercellular junctions, microvilli on the apical membrane, and secretory functions. Liver surface transplanted BVLO showed further BD maturation and connection to the host BD. Taken together, our study developed a novel 3D co-culture method o establish functional human tubular BDs by recapitulating PV-BD interaction.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE198888_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA817246 and SRA study SRP364675. Searching any of these in the dataset finder brings you back here.

Study design
3 × BVLO # vs 2 × LO #

Supports a between-group comparison across 5 samples.

How we read this: 2 replicated groups read from 10 sample titles; they account for 5 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
