Single cell methylome landscapes of mouse embryonic stem cells and early embryos analyzed by reduced representation bisulfite sequencing

We develop a single cell methylome analysis technique based on RRBS, which works robustly for mouse embryonic stem cells (mESCs), sperm, metaphase II oocytes, and zygotes. In total, 36 samples were analyzed, including 8 single mouse embryonic stem cells (mESCs), pooled-5, 10, 20 mESCs, bulk mESCs, 7 single sperms, 10 single pronuclei from 5 individual zygotes, 2 metaphase II oocytes, 2 the first polar bodies and 3 negative controls.
