[Nerve cell clonal lines in culture--models for studying the molecular basis of neuropharmacological actions]
Abstract:
Nerve cell lines with stable properties are isolated from neuroblastomas, glioblastomas or pheochromocytomas by periodic cloning using defined culture media. After the action of different drugs, these cells show all morphological and biochemical signs of differentiation and maturation. Depending on the origin of the clone, the cell lines synthesise typical neurotransmitters, which are stored in vesicles. It is demonstrated on cell lines which synthesise catecholamines that noradrenergic and dopaminergic clones are particularly suitable test objects for basic research in neuropharmacology.
Insights
Stable nerve cell lines derived from tumors can be differentiated into mature cells using drug treatments. These cell lines are valuable tools for neuropharmacology research, particularly for studying neurotransmitter synthesis and function.
