| Title |
Sox8 reprograms ectoderm into ear vesicles and associated neurons [ChIP-seq] |
| Organism |
Gallus gallus |
| Experiment type |
Genome binding/occupancy profiling by high throughput sequencing
|
| Summary |
The vertebrate inner ear arises from a pool of progenitors with the potential to give rise to all the sense organs and cranial ganglia of the head1-6. Here we explore the molecular mechanisms that control ear specification from these progenitors. Using a multi-omics approach combined with loss-of-function experiments we identify a core transcriptional circuit that imparts ear identity, along with non-coding elements that integrate this information. This analysis places the transcription factor Sox8 at the top of the ear determination network. Introducing Sox8 into cranial ectoderm not only converts non-ear cells into ear progenitors, but also activates the cellular programmes for ear morphogenesis and neurogenesis. Thus, Sox8 emerges as a master regulator of ear identity and may be a key factor for sense organ cell reprogramming.

| Overall design |
200 pieces OEP tissue from ss8-9 chick embryos was manually dissected, dissociated and processed for ChIPseq library preparation using antibodies for H3K27Ac, H3K27me3 and H3K4me3.
