METHODS: The calvarium bone of newborn rats was digested with bacterial collagenase and cultured to obtain osteoblasts and SP with different concentrations was then added. The proliferation and activity changes of the osteoblasts were identified by counting the cells, determining the ALP activity and observing the changes of cell cycle.

采用新生大鼠颅盖骨消化法培养成骨细胞，再加入不同浓度的SP，观察细胞生长数量，测定碱性磷酸酶活性及观察细胞周期变化。
