Forskolin was tested for its co-activating ability to enhance the function of fibroblast growth factor (FGF) 8 on dopaminergic (DAergic) differentiation from human fetal mesencephalic neural progenitor cells (NPCs). When NPCs were treated with FGF8 alone, the DAergic phenotype was expressed lightly. The addition of 10 microM forskolin increased the number of DAergic neurons, cooperating with 50 ng/ml FGF8. These cells produced neurotransmitter DA, which was measured by high-performance liquid chromatography. Reverse transcriptase-polymerase chain reaction analysis demonstrated that differentiated cells expressed DAergic development-relative genes tyrosine hydroxylase (TH), nuclear receptor-related factor 1 (Nurr1) and D2 receptor (D2R), indicating that matured DAergic neurons could be obtained under these present conditions. The results suggest that forskolin plus FGF8 may contribute to more efficient production of DAergic neurons from human-derived NPCs for therapy of neurodegenerative diseases.
