Sample type |
SRA |
|
|
Source name |
Extraembryonic endoderm (distal)
|
Organism |
Mus musculus |
Characteristics |
tissue: Extraembryonic endoderm (distal) developmental stage: E6.5 strain: CD1 genotype: WT
|
Growth protocol |
Wild type CD1 mice were housed under conditions approved by the local authorities, and embryos were collected from natural mating.
|
Extracted molecule |
genomic DNA |
Extraction protocol |
Embryos were collected into ice-cold M2 medium (Merck MR-015-D), bisected at the embryonic-extraembryonic border, washed in three drops of HBSS and incubated for 15 min at 4º C in 0,5% Trypsin, 2,5% Pancreatin dissolved in PBS. The distal extraembryonic endoderm (exEndo 1) was manually separated from the epiblast by drawing the distal half through a narrow glass capillary. Pooled exEndo 1 tissues were collected in Lysis buffer (10 mM Tris-HCl (pH=8.0), 10 mM NaCl, 10 mM EDTA, 0.5% SDS, 300 ug/mL Proteinase K). Genomic DNA was isolated by phenol–chloroform extraction. Genomic DNA was sheared in micro TUBE AFA Fiber Pre-Slit Snap-Cap tubes (Covaris 520045) followed by phenol–chloroform extraction. The purified DNA was bisulfite-converted using the EZ DNA Methylation-Gold Kit (Zymo D5005), and WGBS libraries were processed using the Accel-NGS Methyl-seq DNA library kit (Swift Biosciences 30096) following the manufacturer’s recommendations. Libraries were cleaned using Agencourt AMPure XP beads. Quality and concentration of the obtained libraries were measured using Agilent High Sensitivity D5000 ScreenTape on an Agilent 4150 TapeStation. Libraries were then sequenced using 150 base pair paired-end sequencing on a NovaSeq 6000 platform.

Data processing |
Raw reads were subjected to adapter and quality trimming using cutadapt (version 4.1; parameters: --quality-cutoff 20 --overlap 5 --minimum-length 25; Illumina TruSeq adapter clipped from both reads), followed by trimming of 10 and 5 nucleotides from the 5’ and 3’ end of the first read and 15 and 5 nucleotides from the 5’ and 3’ end of the second read. The trimmed reads were aligned to the mouse genome (mm10 including GFP and mCherry transgenes) using BSMAP (version 2.90; parameters: -v 0.1 -s 16 -q 20 -w 100 -S 1 -u -R). Duplicates were removed using the ‘MarkDuplicates’ command from GATK (version 4.3.0.0; --VALIDATION_STRINGENCY=LENIENT --REMOVE_DUPLICATES=true). Methylation rates were called using mcall from the MOABS package (version 1.3.2; default parameters). Only CpGs covered by at least 10 and at most 150 reads were considered for downstream analyses. Assembly: mm10 (including mCherry and GFP transgenes) Supplementary files format and content: Bigwig file containing methylation rates for CpGs covered by at least 10 and at most 150 reads: <chr> <start> <end> <methylation rate>
