Analysis of chromatin landscapes in early human development reveals epigenetic transition during ZGA
Upon fertilization, drastic chromatin reorganization occurs during human preimplantation development. However, the global chromatin landscape and its molecular dynamics in this period remain largely unexplored. Deciphering such process is crucial for understanding both early human development and in vitro fertilization. Here, we investigated genome-wide chromatin accessibility in human preimplantation embryos by employing an improved ATAC-seq that uses as few as 20 cells. We found widespread acc...

Deep data QC
metadata only · no data-level QC for this typeStandardized, field-standard QC computed by touching the data — every metric states how it was obtained
No quantitative QC rubric exists for this data type yet, so it is deliberately left unscored — this is an honest "not applicable", not a poor rating.
measured = computed from the data · extrapolated/reported = derived or from the repository · dq-1.0 · provisional — verify independently
Scientific quality
Based on hands-on reproduction of the papers that use this dataset. A reproducible paper that stands on this data is positive evidence; a flagged one is a prompt to look closer — never a verdict on the dataset itself without the evidence.
