Fund Project: the National Natural Science and Technology Source Program, No. 2001DEA1006*Abstract: Number of neural stem cells is small. NSCs look like circle or ellipse with or without short neurite, with large nuclear-cytoplasmic ratio and deep karyotin. NSCs have no visible differences with other kinds of cells in appearance, and have no cell surface marker. Currently, there are mainly three aspects to identify NSCs: expression of specific nerve antigen, including nestin, Musashi, transcription factor, and cell adhesion molecules; self-renewal ability including single cell clone analysis, BrdU mark and S phase cell; the potential of multi-direction differentiation including immunocytochemical process and reverse transcriptase polymerase chain reaction.

chromatin：染色质

在不分裂的真核细胞中,这种染色体物质被称为"染色质"(chromatin). 它们是不定形的,且有点随机地分散在整个核中. 但是当细胞准备分裂时,染色质凝集,并组装成因物种不同而数目和形状特异的染色体. 研究从细胞中分离出来的染色质发现,

karyolysis：核溶解

1.细胞核的改变 细胞核的改变是细胞坏死的主要形态学标志,表现为:①核浓缩(pyknosis),即由于核脱水使染色质浓缩,染色变深,核的体积缩小;②核碎裂(karyorrhexis),核染色质崩解为小碎片,核膜破裂,染色质碎片分散在胞浆中;③核溶解(karyolysis),在脱氧核糖核酸酶的作用下,

plasma cell：浆细胞

perinuclear space：核周腔

核被膜是双层膜,膜厚约7~8nm,膜间为宽10~50nm的核周腔(perinuclear space). 2、染色体和染色质 染色质和染色体在化学成分上并没有什么不同,而只是分别处于不同的功能阶段的不同的构型. 染色质是指间期细胞内由DNA、组蛋白和非组蛋白及少量RNA组成的线形复合结构,
