Fig. 3From: Thyroid-stimulating hormone decreases the risk of osteoporosis by regulating osteoblast proliferation and differentiationCell proliferation is regulated by TSH in primary osteoblasts. Osteoblasts cocultured with different concentrations of TSH (0, 1, 10, and 100 mU/mL) were detected at 12, 24, and 48 h by MTT assays. The data are expressed as the means±SDs. *P < 0.05 versus the control group (TSH = 0 mU/mL) at the corresponding time period. ***P < 0.001 versus the control group (TSH = 0 mU/mL) at 48 hBack to article page
