Effect of Total Coumarins of Fructus Cnidii on Osteoblast in Neonatal Rat Calvaria Culture

Qiao Zhang

Abstract

Objective: To study the effects of TCFC on proliferation and osteogenic action of osteoblast in neonatal rat calvaria cultures in vitro. Methods: Osteoblasts were isolated from neonatal rat calvaria through trypsin and collagenase digestion. The proliferation and collagen synthesis were assayed by 3H TdR and 3H proline incorporation. The activity of ALP was measured by p nitrophenyl sodium phosphate assay. The ipriflavone was used as positive control drug.Results: TCFC significantly promoted bone cell proliferation, alkaline phosphatase activity and collage synthesis.Conclusion: TCFC had the anti osteoporosis action by promoting osteoblast proliferation, ALP activity and collage synthesis.
