| Title |
Reference cell pool |
| Sample type |

|
| Source name |
Mouse liver reference cell pool
|
| Organism |
Mus musculus |
| Characteristics |
tissue: liver
strain: C57BL/6
|
| Treatment protocol |
Liver tissue was perfused with collagenase
|
| Growth protocol |
C57BL/6 mice were obtained from the National Institute of Aging (NIA) and liver cells were collected and sequenced without growth
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Single hepatocytes were collected using hand-held capillaries under an inverted microscope
Library construction for RRBS sequencing was done as described by Meissner 2005 (PubMed: PMC1258174), but with MseI as digest vector and add adding 2 ng salmon DNA (samples H1,H2) or 2 ng tRNA cDNA (samples H3,H4) as buffer DNA to stabilize single-cell samples.

| Description |
L1
Reduced Representation BS-Seq (RRBS)
|
| Data processing |
Library strategy: RRBS-Seq
Basecalls were performed using CASAVA version 1.4
BS-Seq reads were preprocessed for better alignment quality using FASTX-toolkit 0.0.13, trimgalore 0.2.2 and cutadapt 1.0
BS-Seq reads were aligned to the mm10 genome using Bowtie2 2.0.0 and Bismark 0.7.6
CpG-Methylation calling was done using Bismark 0.7.6
CpG sites were grouped into regions of 1000 nt's with a minimum coverage of 10 CG sites using R 2.13 with custom scripts
Methylation status and differential methylation between single-cells and reference H1 were assessed using bayesian estimation for a beta-binomial model using R 2.13
Methylating epimutations were called on regions showing low methylation in the reference L1 but high methylation in a single-cell sample using R 2.13
Demethylating epimutations were called on regions showing high methylation in the reference L1 but low methylation in a single-cell sample using R 2.13
Genome_build: mm10
Supplementary_files_format_and_content: GFF listing all regions with methylation and demethylating epimutation were generated using R 2.13
Supplementary_files_format_and_content: GFF scores represent the CG methylation level of each region with epimutations
