Iron repletion or choline supplementation restores dendrite branching of iron-deficient neurons. From the tracings of 18 d in vitro neurons (see Figure 1), the average (A) number and (B) length of dendrite branches were measured and the (C) total branch length was calculated. Data are mean ± SD, n = 61–100 neurons. Groups that do not share a common letter are statistically different by 2-factor ANOVA and Tukey test (P < 0.05). An asterisk (*), if present, indicates a statistically significant effect of iron or choline status. A delta symbol (∂), if present, indicates a statistically significant interaction effect. FID, formerly iron deficient; ID, iron deficient; IS, iron sufficient.
