SOX1 links the function of neural patterning and Notch signalling in the ventral spinal cord during the neuron-glial fate switch.

During neural development the transition from neurogenesis to gliogenesis, known as the neuron-glial (Nu/G) fate switch, requires the coordinated function of patterning factors, pro-glial factors and Notch signalling. How this process is coordinated in the embryonic spinal cord is poorly understood. Here, we demonstrate that during the N/G fate switch in the ventral spinal cord (vSC) SOX1 links the function of neural patterning and Notch signalling.
