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.
