文题释义:
成骨细胞:
是骨形成的主要功能细胞,负责骨基质的合成、分泌和矿化。骨不断地进行着重建,骨重建过程包括破骨细胞贴附在旧骨区域,分泌酸性物质溶解矿物质,分泌蛋白酶消化骨基质,形成骨吸收陷窝;其后,成骨细胞移行至被吸收部位,分泌骨基质,骨基质矿化而形成新骨。成骨细胞在骨形成过程中要经历成骨细胞增殖,细胞外基质成熟、细胞外基质矿化和成骨细胞凋亡4个阶段。很多因素可调节这几个阶段,从而最终调控骨形成。
石菖蒲:拉丁学名Acorus tatarinowii,属天南星科、菖蒲属禾草状多年生草本植物,其根茎具气味。叶全缘,排成二列,肉穗花序(佛焰花序),花梗绿色,佛焰苞叶状。根茎常作药用。生长于海拔20-2 600 m的地区,多生在山涧水石空隙中或山沟流水砾石间。花果期2-6月。分布于亚洲,包括印度东北部、泰国北部、中国等国家。石菖蒲有镇静作用,煎剂或挥发油均能使小鼠自发活动减少,解除单笼饲养小鼠的攻击行为,亦能延长戊巴比妥钠所致的睡眠时间,对阈下催眠剂量的戊巴比妥钠有协同作用,尚能显著延长戊巴比妥钠的麻醉时间。

 

摘要
背景:
研究表明石菖蒲及其活性成分能促进成体神经的发生,对抗衰老和治疗相关神经退行性疾病有良好疗效。
目的:探究中药石菖蒲浸提液对脐血干细胞增殖、成骨分化的影响,从中药学角度为促进干细胞的成骨分化提供新的思路。
方法:采用溶剂提取法提取中药石菖蒲浸提液;流式细胞分选技术分离筛选脐血干细胞;电子显微镜观察脐血干细胞生长情况;CCK8法观察石菖蒲对脐血干细胞增殖的影响;ELISA方法检测石菖蒲对脐血干细胞培养上清液中骨钙素、骨形态发生蛋白2含量的影响;碱性磷酸酶染色试剂盒检测石菖蒲对脐血干细胞中碱性磷酸酶分布表达的影响。
结果与结论:①分选出脐血单核细胞中的脐血干细胞纯度可达到(89.66±3.47)%;②加入石菖蒲浸提液低剂量、中剂量、高剂量培养脐血干细胞24,48,72 h后,干细胞的增殖率明显高于空白对照组(P < 0.05),中剂量组的增殖率高于低剂量、高剂量组(P < 0.05);③加入石菖蒲浸提液培养脐血干细胞5,10,15 d后,上清液中骨形态发生蛋白2、骨钙素的含量明显高于空白对照组(P < 0.05),中剂量组的骨形态发生蛋白2、骨钙素含量高于低剂量、高剂量组(P < 0.05);④碱性磷酸酶染色结果显示,加入石菖蒲浸提液培养干细胞10 d后碱性磷酸酶的分布表达明显高于空白对照(P < 0.05),中剂量组和高剂量组的表达明显高于低剂量组(P < 0.05)。⑤结果提示中药石菖蒲可以促进脐血干细胞的增殖以及其成骨分化。

Abstract:

BACKGROUND: Studies have demonstrated that Acorus tatarinowii and its active ingredients can promote adult neurogenesis, exerting an active role in anti-aging and neurodegenerative disease treatment.
OBJECTIVE: To explore the effects of Acorus tatarinowii extracts on the proliferation and osteogenic differentiation of umbilical cord blood stem cells, thereby providing a new idea for promoting the osteogenic differentiation of stem cells by Chinese medicines.
METHODS: Acorus tatarinowii extracts were obtained via solvent extraction method and flow cytometry sorting technology was used to select the stem cells isolated from human umbilical cord. Then, the umbilical cord blood stem cell proliferation was observed by electron microscope, and the effect of Acorus tatarinowii on the proliferation of umbilical cord blood stem cells was observed by cell counting kit-8. Meanwhile, the impact of Acorus tatarinowii on osteocalcin and bone morphogenetic protein-2 contents in the supernatant of umbilical cord blood stem cells were detected by ELISA; alkaline phosphatas expression was detected using alkaline phosphatase staining kit.
RESULTS AND CONCLUSION: The separation purity of the stem cells from umbilical cord mononuclear cells was (89.66±3.47)%. After low, moderate and high concentrations of cord blood stem cells co-cultured with Acorus tatarinowii extractions for 24, 48 and 72 hours, the stem cell proliferation rate was significantly higher compared with the control group (P < 0.05), and additionally, the proliferation rate of moderate concentration group was significantly higher than that in the low and high concentration groups (P < 0.05). The contents of osteocalcin and bone morphogenetic protein-2 in the stem cell supernatants were significantly higher than those in the control group after co-cultured with Acorus tatarinowii extractions for 5, 10 and 15 days, and which the highest in the high concentration group (P < 0.05). The expression of alkaline phosphatase was significantly higher than that in the control group after umbilical cord blood stem cells co-cultured with Acorus tatarinowii extractions for 10 days, and moreover, the expression of alkaline phosphatase in the moderate concentration and high concentration groups were significantly higher than that in the low concentration group (P < 0.05). In conclusion, Acorus tatarinowii can promote the proliferation and osteogenic differentiation of umbilical cord blood stem cells.
