FIG. 6.

Neurons generated from control NPCs, NPC^0–19 and NPC^11–19, exhibit different morphologies at day 31 of the differentiation protocol. Histogram representing the average maximal distance reached by the longest neurites in neurons generated from NPC^0–19 (A) and NPC^11–19 (B) (paradigms C and D in Fig. 1A). Histogram representing the average sum of crossings in neurons generated from NPC^0–19 (C) and NPC^{11–1 9} (D). Histogram representing the average number of branching in neurons generated from NPC^0–19 (E) and NPC^11–19 (F). Histogram values represent means ± SEM. Statistically significant difference (**p < 0.01; ***p ≤ 0.001; n = 3; one-way ANOVA) between Pb exposure and control conditions.
