PCB 11 enhances dendritic arborization in primary rat cortical neurons. (A) Representative photomicrographs of DIV 9 cortical neurons after 48 h exposure to vehicle (0.1% DMSO) or varying concentrations of PCB 11. (B) Diagram illustrating Sholl rings used to quantify dendritic arborization. (C) Sholl data. Dendritic arborization was also assessed by quantifying the following morphometric parameters per neuron: (D) number of primary dendrites and (E) number of dendritic tips, as determined by dividing the number of dendritic tips by the number of primary dendrites. Data presented as the mean ± SE (n > 70 neurons from 3 independent cultures). *P <.05, **P <.01, ***P <.001 relative to vehicle control. 1 Pixel = 0.65 micrometers.
