Diltiazem promotes human induced sensory (iSensory) neuron axon outgrowth. A, Diltiazem (2 μM) enhances iSensory neuron axon length by ~50 percent on CSPG. B, No effect on axon length is detected on laminin. C, βIII-tubulin immunostaining of iSensory neurons cultured on CSPG for 24 hours in the presence of diltiazem or vehicle. Data are mean ± S.E. n = 3-4. Scale bar, 100 μm. *, p < 0.05, Student’s two-tailed t-test.
