| Sample type |
SRA |

|
| Source name |
OS2GNSCR2
|
| Organism |
Mus musculus |
| Characteristics |
cell line: OS2GNSCR2
cell type: old NSC
genotype: no_TF
age: 2.5-year-old
|
| Growth protocol |
MEFs isolated from E13.5 embryos and tail tip fibroblasts isolated from old mice we cultured in MEF medium (DMEM high glucose supplemented with 10% FBS, 1x NEAA, 1x Glutamax and 1x P/S). Mouse fibroblasts were transduced with M2rtTA lentivirus and Dox-inducible lentiviruses of transcription factors in MEF medium. 24 hours after transduction, the medium was switched to reprogramming medium. The medium switch day was defined as day 0 of reprogramming and cells were further cultured with media change every other day. For mouse iNSC reprogramming, cells were cultured in mNSC medium (DMEM/F-12 medium supplemented with 1x N2, 1x B27, 1x Glutamax, 10 ng/mL bFGF, 10 ng/mL EGF). 1 μg/mL Dox was added for 18 days. Mouse iNSC colonies were picked at day 20 and further expanded in Matrigel-coated plates in mNSC medium.

genomic DNA |
| Extraction protocol |
Genomic DNA (gDNA) of cells was isolated using Quick-DNA Microprep Kit (Zymo, #D3021) following the user guide and quantified using a Nanodrop One spectrophotometer (Thermo Scientific).
The gDNA was digested using MspI, followed by end repair, and dA-tailing. The adapter ligation was performed by using adapters with all cytosines being methylated. After size selection, DNA fragments were bisulfite treated. After the bisulfite conversion, unmethylated cytosines were converted to U and further to T after PCR amplification, while methylated cytosines remained unchanged. After PCR amplification, the libraries were checked with Qubit and real-time PCR for quantification and bioanalyzer for size distribution detection. Quantified libraries were pooled and sequenced on Illumina NovaSeq 6000 platform using 150 bp paired-end sequencing.

| Data processing |
RRBS raw reads were trimmed with Trim Galore (version 0.6.6, -rrbs) followed by alignment to the mouse genome (GRCm38/mm10) using Bismark (version 0.23.1).
Then Bismark coverage files were generated from the deduplicated bam files using Bismark Methylation Extractor (–gzip –bedGraph).
Assembly: mm10
Supplementary files format and content: Bismark Coverage files in a GZIP compressed format (*.bismark.cov.gz).
