We introduce the DCM-time machine (DCM-TM) into human induced pluripotent stem cells (iPSCs) to enable retrospective, genome-wide tracing of transcriptional activity. This system labels active genes and enhancers with DCM methylation marks that are propagated during S-phase. Applied to iPSC differentiation towards definitive endoderm and primitive gut tube, DCM-TM resolves activity dynamics and enables integration with transcription factor networks and CpG methylation profiles. Together, DCM-TM provides a powerful platform for dissecting both healthy and pathogenic embryogenesis.2026/09/11GSE304232GSM9145586GSM9145585GSM9145584GSM9145583GSM9145582GSM914558130173304232Homo sapiens
