From: The value of the hedgehog signal in osteoblasts in fluoride-induced bone-tissue injury
The mRNA expressions of Ihh, Smo, Gli2, and Runx2 in osteoblasts treated with fluoride exposure influenced by Cycl. a–d Exhibit the mRNA expressions of Ihh, Smo, Gli2, and Runx2, respectively, in cultured osteoblasts. *Compared with the control group P < 0.05. #Compared with the low fluoride group P < 0.05
