Abstract:
Objective To explore the effect of icariin on stimulating Smad4 mRNA level in MC3T3-E1 cells. Methods MC3T3-E1 cells were treated by 0 ng/ml, 10 ng/ml, 20 ng/ml, 40 ng/ml icariin respectively. MTT method and population diploid time were applied to observe the cell proliferation. The cell ALP level was measured by atomic absorptiometry and the type Ⅰ collagen was observed by immunohisto-chemistry. RT-PCR was used to find the Smad4 mRNA level in the MC3T3-E1 cells. Results Under the inversion phase contrast microscopy, MC3T3-E1 cells were oligodendrocytes-shaped rich with cell organs. The cells density in 10 ng/ml, 20 ng/ml were higher than those in 0 ng/ml,40 ng/ml. Cell growth curve in 10 ng/ml was higher than other 3 groups and the 20ng/ml was higher than 0 ng/ml, 40 ng/ml groups( P
