Effect of Tongxinluo on the proliferation and differentiation of rat embryonic neural stem cells / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of Tongxinluo in on the proliferation and differentiation of rat embryonic neural stem cells (NSCs).</p><p><b>METHODS</b>NSCs were isolated from 12- to 14-day SD rat embryo and treated with Tongxinluo at different doses, and the proliferation and differentiation of the cells were observed by immunofluorescence staining at different time points.</p><p><b>RESULTS</b>The ratio of embryonic NSCs labeled with nestin decreased soon after Tongxinluo treatment, but increased afterwards. Significant difference was noted in the number of cells labeled with beta-tubulin between Tongxinluo group and the control group 3 and 7 days after the treatment, and also between high-dose and low-dose Tongxinluo groups at 7 days.</p><p><b>CONCLUSION</b>Tongxinluo can induce the proliferation and neuronal differentiation of rat embryonic NSCs, and the effect is related to the dose of Tongxinluo administered.</p>
