Due to system maintenance, the application system, application review by the Data Access Committee will be unavailable during the following period.
Schedule: October 5th (Mon), 2026, 9:00 - October 7th (Wed), 2026, 15:00 (JST)
We apologize for any inconvenience this may cause and appreciate your understanding.

We are currently receiving a large number of applications for data submission, and the review process is taking longer than usual.We sincerely apologize for the delay and kindly ask for your understanding. When submitting an application, we would greatly appreciate it if you could allow sufficient time for the processing.

Following a change to our organizational structure effective April 1, 2026, this division has been renamed from the "Database Center for Life Science, Joint Support-Center for Data Science Research" to the "Database Division for Life Science (DBCLS), BioData Science Initiative (BSI), National Institute of Genetics (NIG)". Where the former name still appears in the guidelines, please read it as the new name.

Research title

DNA Methylation Analysis of Early Human Embryos

Research overview

Aims
To generate single-base resolution DNA methylome maps of human gametes and embryos and uncover DNA methylation dynamics during early human development.
Methods
Whole genome bisulfite sequencing libraries were prepared using the post-bisulfite adaptor tagging (PBAT) method. PBAT libraries were sequenced on the HiSeq 2000 or 2500 platform (Illumina) with 100 bp single-end reads.
Participants/materials
Human oocytes, sperm, preimplantation embryos, and cord blood cells
