摘要:

背景:神经生长因子在维持中枢神经系统神经细胞的存活、分化,促进其生长、发育,维持其功能方面具有不可替代的作用。
目的:观察灯盏花素对SD大鼠大脑皮质体外培养神经元生长的影响,并初步探讨其机制。
方法:取新生SD大鼠胚胎,取其大脑皮质后,对神经元进行原代培养,随机分为3组,其中灯盏花素组加入10 g/L灯盏花素,对照组加入等量生理盐水,正常组不作任何处理,各组又分为24 h、48 h亚组。对24孔板中各组细胞各时间点采集图像,之后采用RT-PCR技术检测神经生长因子、酪氨酸激酶A mRNA的表达变化。对96孔板中各组细胞不同时间点采用MTT检测神经元生长活力。
结果与结论:正常组和对照组在各时间点细胞数、胞体面积、突起长度及细胞活力无明显差异(P > 0.05),但正常组及对照组均有随时间点延长,3个指标均上调(P < 0.05),灯盏花素组细胞数、胞体面积、突起长度及细胞活力均较正常组及对照组升高(P < 0.05)。神经生长因子及TrkA mRNA的表达在正常组和对照组在各时间点无明显差异(P > 0.05),灯盏花素组各时间点较正常组和对照组上调(P < 0.05)。提示灯盏花素促进SD大鼠脑源性神经元的存活、生长,其机制可能是通过上调神经生长因子及其受体TrkA的表达发挥作用。

Abstract:

BACKGROUND: Nerve growth factor plays an irreplaceable role on the survival, differentiation and maintenance of the central nervous system cells, also promote the growth and development of these cells.
OBJECTIVE: To explore effect of Breviscapine on the growth of in vitro cultured neurons in cerebral cortex of Sprague-Dawley rats, and preliminarily investigate the action mechanism.
METHODS: The cerebral cortex of newborn Sprague-Dawley rat embryos was collected, the neurons were primary cultured and randomly divided into three groups: normal control group (no treatment), control group (neurons were cultured with normal saline), Breviscapine group (neurons were cultured with 10 g/L Breviscapine). Furthermore each group was assigned into 24-hour and 48-hour subgroups. Images were captured from the 24-well plates at each time points. RT-PCR was applied to examine the expression of nerve growth factor and TrkA mRNA. MTT was used to detect the neuronal growth at each time point.
RESULTS AND CONCLUSION: There was no difference between normal control group and control group in the cell counts, cell body area, neurite length and viability (P > 0.05), as the time prolonged, all data were raised in the 
two groups (P < 0.05). Breviscapine group showed a higher cell count, cell body area, neurite length and viability than normal control group and control group (P < 0.05). No significant difference was found in the expression of nerve growth factor and TrkA mRNA between normal control group and control group (P > 0.05). At each time point, these data in Breviscapine group were increased compared with normal control group and control group (P < 0.05). Breviscapine can promote the survival and growth of brain-derived neurons in Sprague-Dawley rats, and the mechanism might depend on the up-regulating expression of nerve growth factor and its receptor TrkA.
