There is a large subset of retinal progenitor cells that upregulate the OTX2 gene in the developing retina of the mouse. OTX2 is a homeobox transcription factor important for the development of photoreceptors and bipolar cells. If OTX2 is knocked out, photoreceptors and bipolar cells fail to differentiate. In order for OTX2 to be activated in certain retinal populations, it requires the activity of an enhancer called OTX2ECR2. Past studies demonstrated that retinal progenitor cells that had activity of OTX2ECR2 turned into horizontal cells, which require OTX2 for cell genesis and survival, and photoreceptors which require OTX2 for cell …
