Summary (written by the submitters)
In human embryos, major zygotic genome activation (ZGA) initiates at the 8-cell (8C) blastomere stage, marking the initiation of the ontogenesis program. Recent advancements have demonstrated that human pluripotent stem cells (hPSCs) can revert to 8C-like cells (8CLCs) with totipotency in vitro. However, the key regulators involved this transition remain largely unexplored.
Read the full summary ↓
In this study, we identified OTX2 as a novel regulator repressing the induction of 8C-like cells (8CLCs) from hPSCs. Our findings reveal that OTX2 depletion facilitates the generation TPRX1-EGFP+ totipotent-like stem cells (TLSCs), which closely resemble the transcriptomic profile and chromatin accessibility of 8C blastomeres. Notably, TLSCs with OTX2 depletion exhibit bidirectional embryonic and extraembryonic differentiation potential in forming chimeric embryos. OTX2 influences totipotent state transition by binding at loci of key 8CLC regulator, which function in parallel with DUX4. Collectively, our findings reveal a previously unrecognized function of OTX2 in regulating totipotency and establish a new framework for generating TLSCs from hPSCs in vitro, offering significant insights for stem cell biology and regenerative medicine.

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 GSE287150_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: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1211499 and SRA study SRP557786. Searching any of these in the dataset finder brings you back here.

Study design
18 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 18 sample titles: 18 distinct titles with little repetition. 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.
