查询词典 drg

4DRG was co-culture with sciatic nerve segment in 10鸖 DMEM;the axons were longer and surround the sciatic nerve segment which was regard as anew evidence for chemotropism.

结果：(1)在无血清条件下单独培养的DRG，背根神经节的轴突数目众多，外形纤细弯曲，不成束，并且施万细胞和成纤维细胞稀少，所以可以排除两者对轴突生长的影响，为观察来源于变性坐骨神经段的可溶性因子对轴突生长的作用提供了有利条件；(2)在无血清条件下DRG和变性坐骨神经段联合培养，①先单独培养DRG，4天后待神经元轴突长出，再与坐骨神经段联合培养，观察到神经元的轴突数目减少，外形挺直，部分轴突之间相互粘附成束；②变性坐骨神经段和DRG同时联合培养，神经元的轴突数目明显减少，外形粗壮，轴突之间相互粘附成束；(3)有血清条件下单独培养DRG，轴突数目较多，外形挺直，长短不一，部分神经元的轴突之间相互粘附，施万细胞和成纤维细胞数目众多，观察到的轴突生长情况受到施万细胞和成纤维细胞的直接或者间接的影响。

2DRG co-cultured with sciatic nerve undergoing Wallerian degeneration for 14days in vivo in serum free DMEM/F12,1sciatic nerve segment was added into co-culture system at the first moment,the axons were strong and straight and could adhered to each other,and the number of axons dramatically reduced compared with that of DRG cultured alone in serum free medium.2DRG cultured in serum free DMEM/F12for 4days,then the sciatic nerve segment was added into the culture system for 3days,the axons became straight and part of them adhered to each other.

分别在无血清和有血清的条件下将新生鼠的背根神经节和体内变性14天的大鼠坐骨神经段进行联合培养作为实验组，并以在相应条件下单独培养的DRG的轴突的生长情况作为对照组来观察比较轴突的生长情况。
