Cebp’s cell fate outputs diverge in fibroblasts, embryonic stem cells, and B cells because sequence spillover and partner availability reshape enhancer usage, yielding adipocyte, trophectoderm, or myeloid fates.
- Why it matters: Transcription factors have many targets, but it is unclear how a single factor selects which developmental gene programs a cell actually adopts during transitions.
- What they did: Cebp, Cebp{beta}, or Cebp{delta} were expressed alone or with Oct4, Sox2, Klf4, and cMyc, and fate outcomes were mapped; Cebp binding was analyzed for clustered versus low-copy motif spillover, and partner factors like Spi1 or TFAP2C were supplied.
- The result: Increasing Cebp levels altered enhancer creation without changing motif preference, and in fibroblasts Cebp redistributed Oct4, Sox2, and Klf4 to block iPSC formation; adding Spi1 or TFAP2C rewrote outputs via partner-specific enhancer programs.
