title: Neurotrophic effects of FPF-1070 (Cerebrolysin) on cultured neurons from chicken embryo dorsal root ganglia, ciliary ganglia, and sympathetic trunks.
abstract: We examined the effect of FPF-1070 (Cerebrolysin) on neurite outgrowth in explant cultures of dorsal root ganglia (DRG), sympathetic trunks (ST), and ciliary ganglia (CG) from 10- to 11-day chicken embryos. FPF-1070 significantly promoted neurite outgrowth in DRG and ST neurons at all concentrations examined, in comparison with phosphate buffered saline-treated negative controls; however, this effect on neurite outgrowth was not as significant as that observed for nerve growth factor-treated positive controls on DRG and ST neurons. Additionally, FPF-1070 exhibited an inverted U relationship between concentration and effectiveness in DRG and ST neurons. In contrast, FPF-1070 did not affect neurite outgrowth in CG neurons although ciliary neurotrophic factor-treated positive controls showed striking neurite outgrowth. Our results demonstrate that FPF-1070 has different neurotrophic effects depending on the subpopulation of neurons. This study clarifies a role for neurotrophic activity in the mechanism of action of FPF-1070.
