Figure 4

Analysis of the morphological measurements generated by Neuronmetrics™: a, number of dendritic branches per cell; b, length of the longest dendrite; c, cell body area; d, area of dendritic arbor. In each graph the number of days in vitro (DIV) is represented along the x-axis. Data from neurons grown on WT astrocytes are represented by the solid bars, and from neurons grown on Fmr1-/- astrocytes are represented by the white bars. Data are presented as mean ± s.e.m. of 150 neurons from three independent experiments. *, significantly different at P < 0.05; ***, significantly different at P < 0.001; Mann Whitney U Tests (two-tailed).
