Investigation of Pentylenetetrazol (PTZ)-induced toxicity in primary cortical neurons. (A) Immunofluorescence detection of primary neuronal cells and bright field of the same area. Cells were stained with mouse anti-MAP2 antibody (green) and rabbit anti-GFAP antibody (red, detection of astrocytes). The nuclei are stained with DAPI (blue). (B) Observation of morphological changes of neurons using a contrast microscope at 7 days in vitro (DIV). The cells were treated with 0, 7.5, 15, 30, and 60 mM PTZ for 24 h at 7 DIV. (C) PTZ-induced cellular toxicity in neurons. Cell viability is presented as a percentage of control, and each value represents the mean ± SD of three independent experiments. Bar: 100 μm.
