The effect of four compounds of astragalus isoflavones on the differentiation of PC 12 cells / 药学实践杂志

ABSTRACT

Objective To investigate the effects of calycosin, formononetin, calycosin-7-glucoside and ononin on PC 12 cells differentiation. Methods PC 12 cells were cultured and treated with different concentrations of nerve growth factor (NGF), calycosin, formononetin, calycosin-7-glucoside and ononin for 5 days, once a day, 3 times in a row. The neurite outgrowth of PC 12 cells was observed and the expression of β III-tubulin were measured by immunofluorescence. Results Compared with the vehicle group, neurite outgrowth and the expression of β III tubulin in PC 12 cells had not promoted by calycosin, formononetin, calycosin-7-glucoside and ononin (0.01-10.00 μmol/L). Conclusion PC 12 cells differentiation could not be induced by calycosin, formononetin, calycosin-7-glucoside and ononin.
