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
Mus musculus (mouse)
Samples
20 samples: 4 × E11.5 head, chimera vs 4 × E11.5 body, chimera vs 3 × E9.5 head, chimera vs 3 × E9.5 body, chimeraGroups 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)
Organ shortage remains a major challenge in transplantation medicine. Interspecies blastocyst complementation offers a promising strategy to generate human organs in livestock. However, efficient xenogeneic donor cell engraftment remains challenging. Here, we identify an innate immune barrier wherein host macrophages selectively eliminate viable xenogeneic donor cells, a process we term xenophagocytosis.
Read the full summary ↓
Mechanistically, xenogeneic cells display elevated phosphatidylserine, an "eat-me" signal recognized by host macrophages through phagocytic receptor Axl. We demonstrate three orthogonal strategies for xenophagocytosis blockade: genetic ablation of macrophages or Axl receptor in the host embryo, or overexpression of “don’t eat me” signal CD47 or the phosphatidylserine-regulating flippase ATP11C in donor cells. Xenophagocytosis blockade enhances rat and human donor chimerism in mouse embryos and improves interspecies pancreas complementation efficiency. These findings reveal a previously unrecognized innate immune barrier that safeguards species integrity during early embryogenesis and provide mechanistic insights to enhance xenogeneic chimerism for generating human organs in livestock.

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 GSE330329_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.

Raw reads on ENA ↗

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.

Supports a between-group comparison across 14 samples.

How we read this: 4 replicated groups read from 20 sample titles; they account for 14 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.
