The interconversion between naive and primed; pluripotent states is accompanied by drastic epigenetic; rearrangements. However; it is unclear whether; intrinsic epigenetic events can drive reprogramming; to naive pluripotency or if distinct chromatin states; are instead simply a reflection of discrete pluripotent; states. Here; we show that blocking histone H3K4; methyltransferase MLL1 activity with the small; molecule; inhibitor MM-401 reprograms mouse epiblast; stem cells (EpiSCs) to naive pluripotency. This reversion; is highly efficient and synchronized; with more; than 50% of treated EpiSCs exhibiting features of; naive embryonic stem cells (ESCs) within 3 days. Reverted; ESCs reactivate the silenced X chromosome; and contribute to embryos following blastocyst injection; generating germline; competent chimeras.; Importantly; blocking MLL1 leads to global redistribution; of H3K4me1 at enhancers and represses lineage; determinant factors and EpiSC markers; which; indirectly regulate ESC transcription circuitry. These; findings show that discrete perturbation of H3K4; methylation is sufficient to drive reprogramming to; naive pluripotency.
