title: Granulocyte colony-stimulating factor is not protective against selective dopaminergic cell death in vitro.
abstract: In the present study, we evaluated the potential neuroprotective effect of granulocyte colony-stimulating factor (G-CSF), a hematopoietic growth factor in two different culture models in which dopaminergic (DA) neurons die selectively: first, in a culture model in which death of DA neurons occurs spontaneously and second, in a toxin-based paradigm, the in vitro 1-methyl-4-phenylpyridinium model of PD. In neither of the two models, a treatment with G-CSF, could prevent or halt the progressive neurodegeneration. However, we cannot rule out that G-CSF might exert neuroprotective or even deleterious effects in in vivo models of PD, based on the significant increase in the number of microglial cells observed after G-CSF treatment.
