| Source name |
Trophoblast stem cells
|
| Organism |
Mus musculus |
| Characteristics |
condition: WT
|
| Treatment protocol |
TSCs (TSC2 line, clone 5) wild type cells were sorted as single cells onto gelatin and MEF-coated 96-well plates containing ESC medium. Cells were expanded and MEF-depleted for methylation analysis by RRBS.
|
| Growth protocol |
TSCs (TSC2 line, clone 5) were cultured in TSC medium (RPMI+GlutaMAX (Thermo, #61870044), 20 % fetal bovine serum (PAN, #P30-2602), 1 mM sodium pyruvate (Thermo, #11360070), 100 µM 2-mercaptoethanol (Thermo, #21985023) and 1X Penicillin/Streptomycin (Thermo, #15140122); 25 ng/ml FGF4 (R&D systems, #235-F4-025) and 1 µg/ml Heparin (Sigma, #H3149).

| Extracted molecule |
genomic DNA |
| Extraction protocol |
The DNA was extracted using the PureLink Genomic DNA Mini Kit (Thermo, #K182002) according to manufacturer’s instructions.
Concentration of genomic DNA (gDNA) was quantified using a Qubit 3.0 Fluorometer. RRBS was performed on 100 ng gDNA of each sample using the NuGen Ovation® RRBS Methyl-Seq System (Tecan, #0353) following the manufacturer’s recommendations with the following modifications (6). After the final repair step, the bisulfite conversion of DNA was conducted using the Qiagen EpiTect Fast Bisulfite Conversion kit (Qiagen, #59824) following the manufacturer’s recommendations, eluting the bisulfite converted DNA in 23 µl EB. Libraries were amplified with 12 cycles of PCR. Amplified library purification with Agencourt RNAclean XP beads (Beckman Coulter, #A63987) was performed twice (1X). The purified libraries were quality-assessed on an Agilent 4150 Tape-Station HS D1000 ScreenTape and sequenced for 100-bp single-end reads on the NovaSeq6000 (Illumina).

| Data processing |
Raw reads were subjected to adapter and quality trimming using cutadapt (version 2.4; parameters: --quality-cutoff 20 --overlap 5 --minimum-length 25; Illumina TruSeq adapter), followed by NuGEN diversity adapter trimming (https://github.com/nugentechnologies/NuMetRRBS).
The trimmed reads were aligned to the mouse genome (mm10) using BSMAP (version 2.90; parameters: -v 0.1 -s 12 -q 20 -w 100 -S 1 -u -R -D C-CGG).
Aligned reads were deduplicated based on unique molecular identifiers (UMIs) using NuDup (https://github.com/nugentechnologies/nudup; parameters: --start 6 --length 6). Methylation rates were called using mcall from the MOABS package (version 1.3.2; default parameters).
All analyses were restricted to autosomes and only CpGs covered by at least 10 and at maximum 150 reads were considered for downstream analyses.
