Distribution of NPE cells in the cell cycle phases after treatment with bicuculline.

<p>Flow cytometry analysis of PI labelled NPE cells. Graphs are showing PI fluorescence intensity (DNA content) per event. (A) Control cells (1 µM GABA) and (B) bicuculline-treated cells (20 µM bicuculline, 1 µM GABA). Red peaks from left: G₁-, and G₂-phase. Tables list the percentage of cells present in the cell cycle phases calculated by the ModFit LT DNA analysis software.
