Classification criteria for SGZ cells in stages of neurogenesis

Cell type	Morphology	Ki67 immunoreactivity	DCX immunoreactivity
NSC	Triangular soma, single projection through GCL, tuft of very fine processes terminating in inner molecular layer	Rarely positive	Negative
TAP	Irregular soma, no process	Positive	Negative
Neuroblast	Irregular soma, no/small process	Positive	Positive
Immature neuron	Round soma, process extends through GCL	Negative	Positive
Neuron	Round soma, projections through GCL, full dendritic tree extending through entire molecular layer	Negative	Negative
