Genomic DNA for RRBS library generation was isolated and quantified using previously described methods (Boyle et al., 2012)
RRBS library generation was performed as previously described (Boyle et al., 2012). Genomic DNA was enzymatically sheered using MspI endonuclease (New England Biolabs, catalogue number R0106L), which exposes a CpG site at the 3’-end. Barcoded Illumina sequencing adapters were added to each end of the DNA strand. The DNA was then subjected to two rounds of sodium bisulfite conversions using the Epitect Bisulfite Conversion Kit (Qiagen, catalogue number 59104). A final, large-scale PCR was conducted on the converted DNA (which uracil is replaced by thymine) and the product was submitted for sequencing.

| Data processing |
Bulk RRBS processing: Bisulfite-converted reads were aligned to the hg19 reference genome with bsmap using the following parameter: -v 0.05 -s 16 -w 100 -S 1 -R -u -m 0. Methylation rates were called using custom scripts and subsequently filtered for coverage (min 10).
Single cell processing: Adapter clipping and quality trimming using cutadapt. Bisulfite-converted reads were aligned to the hg19 reference genome with bsmap using the following parameter: -v 0.1 -s 12 -q 20 -w 100 -S 1 -R -u -m 0. Methylation rates were called using mcall.
