The Fd4 transcription factor translates transient spatial cues in progenitors into long-term lineage identity.

Scientists discovered a special gene called Fd4 that helps certain brain cells remember who they are supposed to be, even after some important signals go away. This Fd4 gene helps the cells switch on other important genes they need to become special types of neurons. If the Fd4 gene is put in the wrong cells, it can make them turn into the wrong type of neurons.
