Upregulated expression of transcription factors promoting cone identity in late-stage retinal progenitors drives development of the cone-dominant retina of 13-lined ground squirrels.
Even in a simple epithelial tissue that is exposed uniformly to X-ray irradiation, cells show marked differences in their transcriptional response based on their location and cell-cycle status.
