The present study investigated the effects of Quercus infectoria (QI) gall extract on the proliferation, alkaline phosphatase (ALP), osteocalcin, and the morphology of a human fetal osteoblast cell line (hFOB 1.19).
The cells were cultured in Dulbecco's modified eagle medium F12 supplemented with a 10% fetal bovine serum, a 1% penicillin/streptomycin and were treated with QI at various concentrations (0.1 to 99.0 μg/mL) for 72 hours. The levels of ALP and osteocalcin were measured at day 1, 3, 7, 10, and 14 and were compared among the negative control, pamidronate and QI groups.
The median effective concentration (EC50) of hFOB 1.19 treated with QI was 10.30 μg/mL. This concentration was more effective compared to the control drug, pamidronate (EC50 at 16.09 μg/mL). The ALP and osteocalcin levels of hFOB 1.19 treated with QI from day 7 and onwards were significantly increased in a time and concentration-dependent manner. Interestingly, from day 7 until day 14, the ALP and osteocalcin levels were highest in the cells treated with QI compared to the other two groups. The morphology of cells treated with QI was uniformly elongated, higher in number and over-confluent.
After treatment with QI, cell proliferation enhanced and ALP and osteocalcin levels increased.
本研究调查了没食子(QI)虫瘿提取物对人胎儿成骨细胞系(hFOB 1.19)增殖、碱性磷酸酶(ALP)、骨钙素及细胞形态的影响。
细胞在补充有10%胎牛血清、1%青霉素/链霉素的杜氏改良 Eagle 培养基F12中培养,并用不同浓度(0.1至99.0μg/mL)的QI处理72小时。在第1、3、7、10和14天测量ALP和骨钙素水平,并在阴性对照、帕米膦酸盐和QI组之间进行比较。
用QI处理的hFOB 1.19的半数有效浓度(EC50)为10.30μg/mL。该浓度比对照药物帕米膦酸盐(EC50为16.09μg/mL)更有效。从第7天及以后,用QI处理的hFOB 1.19的ALP和骨钙素水平以时间和浓度依赖性方式显著增加。有趣的是,从第7天到第14天,与其他两组相比,用QI处理的细胞中ALP和骨钙素水平最高。用QI处理的细胞形态均匀拉长,数量更多且过度汇合。
用QI处理后,细胞增殖增强,ALP和骨钙素水平升高。
