Graded NANOG and OCT4 dosage in human embryonic stem cells produces striking non-monotonic up-regulation of on-target lineage genes during definitive endoderm differentiation.
- Why it matters: How varying transcription factor levels shape gene programs is poorly mapped, limiting understanding of how cell identity transitions respond to dosage changes.
- What they did: Using CRISPR interference to systematically titrate NANOG and OCT4 in hESCs, the team profiled transcriptomes with single-cell RNA-seq under self-renewal and definitive endoderm conditions, then modeled Perturb-seq responses.
- The result: Quantitative modeling revealed distinct gene response patterns and a recurring non-monotonic lineage-gene behavior that also appears during the ESC-to-neuroectoderm transition.
