show Abstracthide AbstractTranscription factors play essential roles in cell type specification during differentiation, and small sets of transcription factors can reprogram cell identity. Therefore, we tested the impact of increasing periodicity of aromatic residues on the ability of transcription factors to reprogram cells. Overall design: We performed multiple RNAseq, scRNAseq, TTSlamSeq, and ChIPseq of the cells expressing the WT, "AroLITE" and "AroPERFECT" of CEBPa, HOXD4, NGN2, and MYOD1 proteins after transgene induction to measure differentiation of specific cell lines.
