  "summary": "Cell state transitions involve changes in gene expression programs in conjunction with epigenetic regulation occurring in chromatin. Bivalent chromatin, marked by overlapping active H3K4me3 and repressive H3K27me3, poises key developmental genes during pluripotency for cell type-specific activation during differentiation. However, the molecular mechanisms that activate bivalent genes during…",
