Effects of Solidago virga-aurea var. gigantea Miq. Root Extracts on the Activity and Differentiation of MC3T3- E1 Osteoblastic Cell
2005
The purpose of this study was to examine the ability of alkaline phosphatase (ALP) synthesis of MC3T3-E1 cells when above edible sources, Solidago virga-aurea var. gigantea Miq. root (SVR) extracts, were supplimented. MC3T3-E1 cells were cultured with (vehicle control), dexamethasone and genestein (positive control), and SVR extracts for 27 days. The effects of SVR MeOH extracts and its fractions on cell proliferation were measured by MTT assay. At 10, 100 of SVR methanol extract treated, that were elevated of cell proliferation to 140 and via vehicle control, respectively. And then ALP synthesis was measured by spectrophotometer for enzyme activity and by naphthol AS-BI staining for morphometry at 3, 9, 18, and 27th day. As the results, every extracts and fractions were promoted ALP activity by time course at 1, 10, 100, except n-hexane and chloroform fractions. Remarkably, the MeOH extracts were increased ALP activity more than 4.4 times compared with vehicle control, 2.2 times via positive control at 27th day (p, showed remarkably higher than vehicle-treated control cells of mineralization which were checked by Alizarin red staining. These results indicate that SVR methanol extract have an induction ability of proliferation and differentiation on osteoblast.
