In Part 1 of our research, BGSCs were sorted through immunomagnetic beads marking by CD133 and cultured in vitro, and character as a stem cell was identified by stem cell markers (CD133 and Nestin) and differentiated cell markers [ microtubule-associated protein 2(MAP2), glial acidic fibrillary protein and myelin basic protein] , ultrastructure observing with electron microscopeand engrafting to severe combined immunodeficiency mice for tumorigenesis test. The results were as following: Only a small subset of CD133+ glioma cells in glioma cell lines and fresh specimens from various pathologic grade could express stem cell markers CD133 and Nestin, view ultrastructure of a stem cell and be capacity of serial passage in culture. These CD133+ cells possese a marked capacity for multipotent differentiation and could differentiate into tumor cells expressing MAP2,β-TubulinⅢ, GFAP and MBP; When engrafted into SCID mice, they can generate and form tumors that phenotypically resembl the tumor from the patient.

在本课题中，在第一部分实验中采用以CD133为标志的免疫磁珠法从人脑胶质瘤组织和细胞株中分离脑胶质瘤干细胞并进行体外培养，通过免疫荧光技术检测干细胞标志物CD133、Nestin，诱导分化后检查分化细胞标志物MAP2、GFAP、MBP以及电镜超微结构观察和移植SCID鼠致瘤实验，对其干细胞特性加以鉴定，得到如下结果：不同病理分级的新鲜胶质瘤标本和胶质瘤细胞株中存在一小部分CD133+的胶质瘤细胞，能表达干细胞的标志物CD133和Nestin，符合干细胞的超微结构特点，体外培养能连续传代；具有多向分化潜能：诱导分化后能产生MAP2、β-TubulinⅢ、GFAP、MBP染色阳性的细胞；移植SCID鼠后能形成与亲本肿瘤表型一致的移植瘤。

One simplified hypothesis is that, when the growth cone detected the directional signal, actin will polymerize asymmetrically in the growth cone, so that the filopodia and lamelipodia will extend preferentially to one side, microtubule will further follow and stabilize this growing direction.

一种假说认为，当轴突生长锥探测到方向性的信号时，生长锥内的 actin成分发生不对称聚合，filopodia及lamelipodia向一侧优先延伸，进而轴突内微管也朝同侧延伸，使生长方向进一步稳定下来。

In recent years,small G proteins have become an intensively studied group of regulatory GTP hydrolyses involved in cell signaling, which take part in numerous and diverse cellular processes, such as gene expression, cytoskeletal reorganization ,microtubule organization, and vesicular and nuclear transport, functioning as molecular switches.
