Single-cell multi-omic detection of DNA methylation and histone modifications reconstructs the dynamics of epigenetic maintenance

DNA methylation and histone modifications encode epigenetic information. Recently, major progress was made to measure either mark at single-cell resolution. However, a method for simultaneous detection is lacking, preventing study of their interactions in complex systems. To bridge this gap, we developed scEpi2-seq. This technique provides single-molecule and single-cell readout of histone modifications and DNA methylation and reveals how DNA methylation maintenance is influenced by the local chromatin context.
