Figure 1From: Comparison of P2X and TRPV1 receptors in ganglia or primary culture of trigeminal neurons and their modulation by NGF or serotonin Survival of neurons in TG ganglia or in culture. Survival of neurons (calculated as neuron density expressed as number of β-tubulinIII positive cells per unit area) at 1–4 days in culture. Data are normalized with respect to those at 1 day (n = 250). *: P < 0.05.Back to article page
