Abstract

Abstract : Abstract: Traditional Chinese medicines are used in promotion of fractured bone healing and bone diseases. Some studies reported total flavonoids from plant can be used as an auxiliary source of exogenous. Use different methods to identify and verify effects of total flavonoids from Arachniodes exilis (TFAE) on human umbilical cord mesenchymal stem cells (HUCMSCs) in vitro. Concentrations of 1 and 5 μg/mL TFAE significantly increased ALPase activity in HUCMSCs compared to the other concentrations at days 3 and 7 ( P < .05). RT-PCR showed that expression levels of osteogenic genes (Col1a1, OPN, Runx2 and Osx) were remarkably enhanced in HUCMSCs following treatment with different concentrations of TFAE for 9 days compared with 0 μg/mL TFAE group (control). The results showed that concentration < 5 μg/mL of TFAE induced osteogenic differentiation in HUCMSCs Alizarin red staining assays revealed that both TFAE and S1191 was significantly decreased (7.80 ± 0.66) compared with the TFAE group (16.00 ± 0.97) ( P < .01). ALPase activity on days 3 and 7 was relatively lower in HUCMSCs grown in media supplemented with both S1191 and TFAE than that of in TFAE group only. The results indicated that osteogenic markers (Col1a1, OPN, Runx2 and Osx) were significantly downregulated in the TFAE + S1191 group in comparison to the control group. The expressions of Col1a and OPN in the TFAE + S1191 group decreased significantly ( P < .01) by Western blotting. TFAE promotes the odonto/osteogenic differentiation of human UCMSCs via activation of ER.
