OEC co-cultures protected OGD-induced cell damage in mixed neuron-glial cultures. a & d: neuron-glial cultures, (b & e): Con-OEC cocultured with neuron-glial culture, (c & f): PGIS-OEC cocultured with neuron-glial cultures, (g): quantitative bar chart for tubulin-IR density, (h): quantitative bar chart for PI (+) cell numbers in neuron-glial cultures. a-c are tubulin immunoreactive cells, (d-f) are PI (+) cells. Bar = 100 μm. *,** P < 0.01,0.05, compared to neuron-glial cultures. One-way analysis of variance + Bonferroni post test. Data were expressed as mean ± SEM, represent the results of three independent experiments (n =8-10 per experimental conditions)
