Abstract:
Objective To study the effects of Yiqi Huoxue Huatan ( qi-replenishing blood-activating phlegm-resolving) Formula on proliferation and differentiation of rat embryonic neural stem cells ( NSC) . Methods The rat NSC were divided into five groups, including blank serum group, drug serum group, blank serum + LY294002 group, drug serum + LY294002 group, and culture medium control group. The effects of drug serum on cell proliferation and differentiation were evaluated by cell culturing, serum pharmacology, immunofluorescence techniques. Morphological changes were observed by phase contrast microscope. Nestin, neuron-specific enolase ( NES ) and glial fibrillary acidic protein ( GFAP ) were measured by using immunofluorescence staining. Results Morphologically, drug serum was non-toxic to neural stem cells and promoted the differentiation of neural stem cells. Immunofluorescence staining showed that nestin expression increased within 24 h yet decreased significantly after 72 h incubation. NES and GFAP positive cells increased significantly in the drug serum group, compared with control group. Conclusion The serum from the rats treated with Yiqi Huoxue Huatan Formula has significant effects on differentiation and proliferationof NSC.
