Effect of taurine on human fetal neuron cells: proliferation and differentiation.
The purpose of this study was to investigate the effect of taurine on human fetal brain neuron cell proliferation and differentiation using a glial-free, pure cerebral neuronal culture grown in a serum-free environment. We found that taurine was necessary for neuronal survival and neurite extension. Taurine, on the other hand, has a trophic effect on the human fetal brain cell, promoting both proliferation and differentiation. Results showed that DNA synthesis of the neurons was increased in a dose-dependent manner when neurons were cultured in the medium containing taurine (100-6400 microM). The protein content of neuronal cells was also significantly increased in the neurons treated with taurine as compared to the control. At day 15, the expression of neuron-specific enolase (NSE) was only detected in the neurons cultured in the medium containing taurine. These results establish taurine as a putative human fetal brain neurontrophic factor in the process of human brain development.
