Calcium sulfate has been used for bone regenation in oral medicine. Osteopontin, a marker molecule, expressed by osteoblast, plays multiple roles in human body. However, the effect of calcium sulfate on osteopontin expressed in osteoblasts is unclear. In this study, U-2 osteosarcoma osteoblastic cells were cultured in 0, 0.5, 1, or 10 μM calcium sulfate hemihydrate. There was no effect in the proliferation of cells, suggesting that calcium sulfate up to 10 μM is biocompatible. The cells and conditioned media were collected for analyzing mRNA and protein levels of osteopontin by reverse-transcription polymerase chain reaction and Western blot, respectively.
