喂饲补肾中药大鼠的血清对成骨细胞的生物学作用

目的 探讨喂饲补肾中药大鼠的血清对体外培养的成骨细胞的生物学作用。方法 在新生SD大鼠头颅骨第2代成骨细胞培养液中加入不同浓度(低、中、高)的中药血清，并与空白组对照，分别观察成骨细胞的增殖、分化和矿化功能。结果 补肾中药血清具有刺激成骨细胞增殖的作用，可提高碱性磷酸酶活性并增加矿化结节形成的数量。结论 补肾中药血清具有刺激体外培养的成骨细胞增殖及分化成熟的功能。

Biological effect of serum of kidney-tonifying traditional Chinese drug-fed rats on cultured osteoblasts]

OBJECTIVE: To investigate the biological effects of the serum of rats fed with kidney-tonifying traditional Chinese drugs on cultured osteoblasts in vitro. METHODS: The culture media containing the serum from rats fed with the drugs at different doses (high, mediate and low doses) were used to treat the second passage of the osteoblasts from the skull of newborn SD rats, and the cell proliferation, differentiation and mineralization were observed. RESULTS: The serum stimulated the cell proliferation, enhanced alkaline phosphatase activity and increased the number of mineralized nodules in the cultured osteoblasts. CONCLUSION: Kidney-tonifying traditional Chinese drugs can stimulate the proliferation, differentiation and maturation of cultured osteoblasts in vitro.
