part of spinal cord dorsal/ventral patterning ventral spinal cord interneuron differentiation neuron fate commitment ventral spinal cord interneuron fate commitment The process in which the developmental fate of a cell becomes restricted such that it will develop into a ventral spinal cord interneuron. Ventral spinal cord interneurons are cells located in the ventral portion of the spinal cord that transmit signals between sensory and motor neurons and are required for reflexive responses. 2009-05-07T12:21:13Z dph biological_process GO:0060579 cell fate commitment involved in pattern specification
