Early hypoxia modulates the phenotype of dopaminergic cells in rat di- and mesencephalic cell cultures and induces a higher vulnerability of non-dopaminergic neurons to a second hypoxic exposure.

Abstract excerpt

To investigate long-term effects of hypoxia on a cellular level, di- and mesencephalic cell cultures were exposed to hypoxia on in vitro day 2 (incubation in culture medium, pO2 = 10-20 mmHg, 24 h) and on in vitro day 13 (incubation in an electrolyte solution, pO2 = 10-20 mmHg, 8 h). The numbers of neuron-specific enolase immuno-reactive (NSE-IR) and tyrosine hydroxylase immuno-reactive (TH-IR) neurons and the...
