Abstract:
BACKGROUND: There are fewer reports about estrogen effects on bone marrow stromal cells (BMSCs). OBJECTIVE: To study the effect of diethylstilbestrol on the osteogenic differentiation of rabbit BMSCs. METHODS: Rabbit BMSCs cultured in vitro were intervened with 0, 10-7, 10-6, 10-5 mol/L diethylstilbestrol, and BMSCs cultured with dexamethasone 10-8 mol/L, β-sodium glycerophosphate 10 mmol/L, and vitamin C 50 mg/L were used as positive controls. RESULTS AND CONCLUSION: 10-6 mol/L diethylstilbestrol significantly improved the proliferative ability of BMSCs at 24, 48, and 72 hours after intervention (P < 0.01). 10-5 mol/L diethylstilbestrol significantly inhibited the proliferation of BMSCs at 48 hours after intervention as well as 10-7 mol/L diethylstilbestrol at 72 hours (P < 0.01). Mineralized nodular structures formed at 25 days after intervention with 10-7 mol/L diethylstilbestrol. Alkaline phosphatase activities were remarkably increased at 14 and 21 days after intervention with 10-7, 10-6 mol/L diethylstilbestrol. It has been proved that diethylstilbestrol has an enhancing effect on the osteogenic differentiation of rabbit BMSCs.
