SGN cultured from C7-C14 in neurotrophin free medium or medium containing 5 ng/ml of BDNF or NT-3. (A) Percentage of SGN expressing glycine-induced currents significantly reduced (Chi-square test, p = 0.002) in BDNF or NT-3 treated cultures relative to control. (B) Mean amplitude (± SD) of glycine-induced currents recorded from SGN cultured in neurotrophin free medium was significantly (One-way ANOVA, P = 0.003, F(2, 25) = 7.45) greater than in SGN cultured with BDNF or NT-3. A post-hoc analysis showed a significant difference between Control vs NT-3 and Control vs BDNF groups (Tukey’s Multiple Comparison Test, P < 0.05).
