这是人们确知的第一例由于脑内干细胞疗法而导致的脑肿瘤，据报告称科学家之前就预言过这种现象，并在科学美国人杂志和其他地方发表过相关文章。
But this is the first-known case of a brain tumor caused by a brain stem cell therapy, according to the report-a phenomenon scientists have predicted in the pages of Scientific American and elsewhere.
大量事实表明，包括脑肿瘤在内，所有肿瘤细胞群落之间在形态和功能上存在很大差异，其异质性与肿瘤干细胞的分化潜能有关。
There is overwhelming evidence that the tumor clone including brain tumor is heterogeneous with respect to both morphology and function, which indicates differentiation potential of tumor stem cells.
目的探讨脑肿瘤干细胞(BTSC)在体外分化过程中的细胞形态、分化相关标志物表达和增殖动力学变化，为进一步研究BTSC分化走向提供实验依据。
Objective To pursue the changes of cell morphology, expression of differentiation related markers, and proliferation cycles of brain tumor stem cells (BTSCs) after differentiation in vitro.
最后概述了脑肿瘤干细胞学说及其研究的临床意义。
Last, review the brain tumor stem cell and its clinical significance.
我们的研究表明内皮细胞与能够自我更新的脑肿瘤细胞之间存在密切的交互作用，并且能够分泌细胞因子来维持这些细胞的干细胞状态。
We show that endothelial cells interact closely with self-renewing brain tumor cells and secrete factors that maintain these cells in a stem cell-like state.
但重要的是，脑肿瘤干细胞中这些分子呈现显著的过表达。
Importantly, a significant over-expression of these molecules were found in the brain tumor stem cells.
