Proper parental histone allocation is required for mouse embryonic stem cell differentiation and histone post-transcription modification inheritance


ABSTRACT: To understand whether parental histone PTM landscape plays roles in cell differentiation, we perturbed parental histone PTM allocation by mutating histone chaperone MCM2 on its histone binding domain (MCM2-2A mutation), disrupted only the histone transferring of MCM2 protein in mouse embryonic stem cells (ESCs). Combining single-cell transcriptomics and epigenomics with lineage barcoding, we found that MCM2-2A mutant ESCs cannot be fully differentiated to neuronal precursor cells (NPCs), causing by the redistribution of H3K27me3, and subsequently NPC related gene expression. Here, we show that the parental histone allocation plays an important role in the establishment of chromatin landscapes, altering ESC differentiational potential, shaping expression programs and cell heterogeneity.
