nerve stem meaning in English

神经干

3 . to probe into the differentiation route of mscs to neurocyte , the specific mark of nerve stem cell , nestin , was detected by rt - pcr
为了探索msc向神经细胞分化过程中的路径，本研究利用rt - pcr技术检测了诱导前后的细胞对神经干细胞特异性标志nestin的表达。
The result showed that mscs did not express nestin , and induced cells expressed nestin . it suggested that mscs differentiated firstly into nerve stem cells , and then differentiated into neurocyte
结果发现诱导前的msc不表达nestin ，诱导5h后的细胞表达nestin ，表明msc经神经干细胞向神经细胞分化。
In this experiment we will record the compound active potential of the nerve stem , and then we will study some methods to assay the refractory period of the nerve stem and the conduction of nervous impulse
本次实验我们将记录观察蛙坐骨神经干的复合动作电位，并学习神经干不应期和神经冲动传导速度的测定等常用电生理学实验方法。
