Results: ApoD was observed positively expressed in type2 astrocytes and oligodendrocytes from O2A lineage, while it was not expressed in type1 astrocytes from T1A lineage. Accordingly, we can verify the phenomenon found in the study of T1A and T2A gene different expression profile that ApoD mRNA was highly expressed in T2A and lowly expressed in T1A. Conclusion: It can be concluded that lipid metabolism related genes such as ApoD play important roles in the generation and differentiation of O2A lineage, which closely correlate with internal mechanism of lipid metabolism in the brain and myelogenesis.［Key words］astrocyte(T1A, T2A); oligodendrocyte; O2A lineage; apolipoproteinApoD

我们已采用基因芯片技术在mRNA水平研究两型星形胶质细胞的基因表达谱差异，发现ApoD在2型星形胶质细胞中差异高表达，故本文拟用激光共聚焦双重免疫荧光标记技术进一步在蛋白质水平观察ApoD在体外分化成熟的两型星形胶质细胞以及少突胶质细胞中的表达情况，以期为我们深入研究ApoD等脂代谢相关基因在脑内脂质代谢和神经髓鞘发育机制中所起的作用提供有用的实验依据，依此探讨胶质细胞发生和分化的信号机制。
