pubmed:abstractText |
MN9D is an immortalized dopamine-containing neuronal hybrid cell line. When MN9D cells were coaggregated with primary embryonic cells of optic tectum, a brain region that does not receive a dopaminergic innervation, there was a marked reduction in their dopamine content, tyrosine hydroxylase immunoreactivity, and tyrosine hydroxylase mRNA. Similar reductions in dopamine content were produced by coaggregation with cells from embryonic thalamus, another brain region devoid of dopaminergic innervation. Coaggregation of MN9D cells with dopaminoceptive cells from the corpus striatum or the cortex did not have a demonstrable stimulatory effect on the dopamine content of MN9D cells. The decrease in MN9D dopamine content produced by optic tectum cells was not reversed by addition of corpus striatum cells. Thus, the MN9D hybrid cells are able to respond to an inhibitory factor(s) from cells derived from brain areas that are not targets for dopaminergic neurons. Catecholamine-producing PC12 cells did not respond in a similar manner, suggesting that the response of MN9D cells is a function of their mesencephalic origin. Given the selective response of MN9D cells to different brain cell populations, this hybrid cell line should facilitate investigations of cell-cell interactions in the central nervous system that may be involved in the expression of neurotransmitter phenotype and establishment of specific neuronal connections.
