This article will visually present the differentiation of newborn mouse derived stem cells to early oocyte-like cells. Biology Single Oocyte Bisulfite Mutagenesis Michelle M.

Our modified protocol allows for DNA methylation analysis at the single-cell level and was specifically designed for individual oocytes. It can also be used for cleavage-stage embryos.
