Supported by: the Youth Foundation of National Natural Science Foundation of China, No. BACKGROUND: Bone marrow mesenchymal stem cells of mice are different from human and rats. The difficulties of culture, sustaining impermanency activity of BMSCs after passage and short-term effect of stem cells tracking limited the study of mice.

摘要背景：小鼠骨髓间充质干细胞培养不同于人及大鼠，培养扩展难度高，传代后干细胞活性保持时间短；又鉴于干细胞本身特点，使现有干细胞示踪方法作用时间短，这些因素均影响小鼠骨髓间充质干细胞的实验研究。

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.

由于神经干细胞的数量很少，从细胞形态来看神经干细胞为圆形或椭圆形，无或有较短的突起，核质比大，核染色较深，形态上与其它种类的细胞没有明显的差异，并且未找到一种细胞表面特异性标志物，因此目前鉴定神经干细胞主要有以下3个方面：特异性神经抗原的表达，包括巢蛋白、Musashi、转录因子及细胞黏附分子；自我更新能力，包括单细胞克隆分析、BrdU标记S期细胞；多向分化潜能，包括免疫细胞化学法、聚合酶链反应色法。
