A dopaminergic neuronal cell line was established which stably expressed human Bcl-2 (MN9D/Bcl-2) or a control vector (MN9D/ Neo). Overexpression of Bcl-2 cells led to robust neurite formation without cessation of cell division. Most markers of neuronal and/or dopaminergic maturation were unchanged although the synaptosomal associated protein, SNAP-25, was increased three-fold in MN9D/ Bcl-2 cell lines. These data support a role for Bcl-2 in developmental processes at least during a certain stage(s) of neurogenesis.
