Neurite outgrowth response to DSD-1-PG/mouse phosphacan in the presence of PORN depends on neuronal lineage. Shown is a summary of neurite outgrowth assays comparing the effect of DSD-1-PG coated on PORN on hippocampal neurons (HCN) and dorsal root ganglion explants (DRG). A, The percentage change in neurite-bearing cells/explants versus the PORN control;B, the percentage of neurite outgrowth versus PORN. In the case of hippocampal neurons the length of the longest neurites was measured, whereas for the DRG explants, the surface area of the halo in square millimeters was measured. At least three independent experiments were analyzed, and the mean values of the neurite lengths/halos and percentage of neurite-bearing cells/explants were compared byt test. n.s., Nonsignificant; ** 0.01 > p > 0.001. Error bars represent the SE.
