摘要:

背景:研究表明补阳还五汤对各种细胞均有保护作用,但机制尚不清楚,有研究推测是它的生物碱有效部位起作用。
目的:观察补阳还五汤生物碱有效部位对人脐血干细胞体外增殖的影响。
方法:获取临床健康产妇的新鲜脐血,制备人脐血干细胞悬液,将纯化的人脐血干细胞接种于40个培养皿中进行传代。分组:川芎嗪组给予100 g/L川芎嗪,阿魏酸组给予50 g/L阿魏酸,生物碱有效部位组(川芎嗪+阿魏酸组)给予100 g/L川芎嗪+ 50 g/L阿魏酸;对照组:继续用含体积分数为20%小牛血清的DMEM培养液培养。培养2,4,6,8,10 d观察人脐血干细胞增殖情况;24,72 h后流式细胞仪测定S期细胞的比例,培养10 d后电流钳模式记录细胞静息膜电位变化。
结果与结论:川芎嗪组和阿魏酸组人脐血干细胞的增殖作用不明显,培养10 d时生物碱有效部位组细胞增殖情况明显高于川芎嗪组、阿魏酸组和对照组(P < 0.01)。生物碱有效部位组在培养24,72 h后处于S期的人脐血干细胞明显增多;川芎嗪+阿魏酸组细胞静息膜电位高于川芎嗪组、阿魏酸组和对照组(P < 0.01)。提示补阳还五汤生物碱有效部位能促进人脐血干细胞的体外增殖。

Abstract:

BACKGROUND: Studies have shown that Buyang Huanwu decoction has protection effect on various cells, but the mechanism is unclear. Some studies have speculated that the alkaloids of Buyang Huanwu decoction play a role.
OBJECTIVE: To observe the effect of alkaloid of Buyang Huanwu decoction on the in vitro proliferation of human umbilical cord blood stem cells.
METHODS: Fresh umbilical cord blood was obtained from healthy puerperant to prepare the human umbilical cord blood stem cells suspension, then the purified human umbilical cord blood stem cells were seeded into 40 culture dishes for passage. The cells were divided into four groups. The cells in the tetramethylpyrazine group were cultured with 100 g/L tetramethylpyrazine, the cells in the ferulic acid group were cultured with 50 g/L ferulic acid and the cells in the alkaloids group (tetramethylpyrazine+ferulic acid group) were cultured with 100 g/L tetramethylpyrazine and 50 g/L ferulic acid; cells in the control group were continuously cultured with Dulbecco’s modified Eagle’s medium containing fetal bovine serum with the volume fraction of 20%. The proliferation of human umbilical cord blood stem cells were observed after cultured for 2, 4, 6, 8 and 10 days; after cultured for 24 and 72 hours, the ratio of human umbilical cord blood stem cells in S phase was determined by flow cytometry, and after cultured for 10 days, the resting membrane potential changes were recorded with current clamp mode.
RESULTS AND CONCLUSION: The proliferation of human umbilical cord blood stem cells in the tetramethylpyrazine group and ferulic acid group was not obvious; after cultured for 10 days, the proliferation of human umbilical cord blood stem cells in the alkaloids group was significantly higher than that in the tetramethylpyrazine group, ferulic acid group and control group (P < 0.01). After cultured for 24 and 72 hours in the alkaloids group, the number of human umbilical cord blood stem cells in S phase was increased; the resting membrane potential in the alkaloids group was higher than that in the tetramethylpyrazine group, ferulic acid group and control group (P < 0.01). The results indicate that the alkaloid of Buyang Huanwu decoction can promote the proliferation of human umbilical cord blood stem cells.
