Title |
STEM-seq IVC+4d Epi rep2 |
Sample type |
SRA |
|
|
Source name |
In vitro culture embryo
|
Organism |
Mus musculus |
Characteristics |
strain: C57BL/6N x DBA/2N tissue: Epiblast
|
Treatment protocol |
C57BL/6N female mice were induced for superovulation by injections of 5 IU of pregnant mare’s serum gonadotrophin and 5 IU of human chorionic gonadotrophin (44-48 hours apart) and mated to DBA/2N males. Embryos were flushed out from uterus at E4.5 and cultured 1, 2 or 4 days in CMRL 1066 supplemented with 1mM glutamine, 1mM sodium pyruvate and 20% fetal bovine serum.

Extracted molecule |
genomic DNA |
Extraction protocol |
Embryos were washed with PBS and incubated in lysis buffer. STEM-seq libraries were constructed following the protocol described in this study (Zhang et al., Nature Genetics, 2017).

Description |
Processed data file: stage.bed.gz in STEM-seq_methylation_bedgraph_files.tar.gz.
|
Data processing |
Base calls were performed using CASAVA version 1.8. Early embryo STEM-seq reads were aligned to the mm9 genome using BSseeker2.0.8. Replicates of same stage were pooled together and methylation values in wiggle files were computed for each single base. ES cell STEM-seq and MethylC-seq reads were aligned to the mm9 genome using BSseeker2.0.8. Replicates of same stage were pooled together and methylation values in wiggle files were computed by the number of reads falling into 1,000bp bin in the genome.
Genome_build: mm9.
Supplementary_files_format_and_content: The bedgraph files counted the number of reads falling on each base or 1,000bp bin in the genome.
