radial cell

AIM: To search the evidences for whether cholinergic neuron is derived from radial glial cell in developing telencephalon, and study the relationship of ontogeny of cholinergic neuron and differentiation of neural stem cell.

目的：为在端脑发育中胆碱能神经元是否来源于放射状胶质细胞寻找实验证据，以分析胆碱能神经元发生与神经干细胞分化之间的关系。

In the axial systems, the phloem consists of sieve cells, phloem parenchyma cells, albuminous cell and phloem fibers. In the radial systems, it consists of phloem rays.

轴向系统由筛胞、韧皮薄壁组织细胞、蛋白细胞和韧皮纤维组成，径向系统由韧皮射线组成。

No significant differences in tangential and radial width of cambial fusiform cell, length of vessel element, ratio of fiber and ray tissue were found among different stages.

结果表明，形成层纺锤形细胞的径向和弦向宽度在活动期不同阶段差异不显著，而纤维长度、纤维宽度、壁腔比、微纤丝角、导管分布频率和胞壁率差异极显著；

Meanwhile, the radial width of cambial fusiform cell had negative correlations with fiber length, ratio of fiber length to width and ratio of ray tissue, and a positive correlation existed between tangential width of cambial fusiform cell and fiber width.

形成层纺锤形细胞的径向宽度与纤维长度、纤维长宽比和射线比量呈显著负相关；形成层纺锤形细胞的弦向宽度与纤维宽度呈显著正相关。
