decreased neuron apoptosis ( J:176956 )
• in culture following NGF withdrawal
• 1.7-fold at E15.5 in the dorsal root ganglia
abnormal neuron differentiation ( J:176956 )
• in culture, dorsal root ganglia exhibit reduced axon degeneration following NGF withdrawal compared with wild-type cells
• however, dorsal root ganglia axon outgrowth is normal
abnormal dorsal root ganglion morphology ( J:176956 )
• increase in number 1.8-fold at E17.5
