摘要: 为研究佛手柑内酯对大鼠成骨细胞增殖、分化的影响。原代培养新生大鼠颅骨细胞,利用MTT法、微量酶标法、酶联免疫吸附法(ELISA)、qPCR等方法分别测定不同浓度佛手柑内酯对大鼠成骨细胞增殖,碱性磷酸酶(ALP),骨钙素(BGP),Ⅰ型胶原mRNA(CollagenⅠmRNA)表达的影响。结果显示,与对照组相比,佛手柑内酯作用于细胞24、48、72 h均对成骨细胞的增殖有促进作用(P<0.05);作用48、72 h均能促进ALP、BGP、CollagenⅠmRNA表达(P<0.05)。表明佛手柑内酯可促进大鼠成骨细胞的增殖和分化,为防治骨质疏松症的新药研究提供理论依据。

Abstract: To study the effects of bergapten (5-MOP) on proliferation and differentiation of cultured osteoblasts in vitro,MTT,microtitration assay,enzyme-linked immunosorbent method (ELISA) and qPCR were used separately to observe the proliferation,the activity of ALP and the content of osteocalcin and mRNA expression of collagen I of osteoblasts cultured in vitro with bergapten (5-MOP) of different concentrations in it for different incubation periods.The effect of promoting proliferation of rat osteoblasts cells in vitro after 24 h and 48 h and 72 h was more marked by the groups of bergapten (5-MOP) compared with the control group.The activity of alkaline phosphate (ALP) and secretion of osteocalcin (BGP) and mRNA expression of collagen I were stimulated by bergapten (5-MOP) after 48 h and 72 h incubation.It was demonstrated that bergapten (5-MOP) had the effects on stimulating the proliferation and differentiation of cultured osteoblasts in vitro.

Key words: osteoblast, proliferation, differentiation, bergapten
