" B2 y" j4 q4 }4 m  \0 V一种大量表达的分子能成为肿瘤起始细胞（CIC——又称肿瘤干细胞）的可靠标记分子吗？肿瘤起始细胞在肿瘤实体细胞中含量较少。CD44已经成为几种造血和内皮起源的恶性肿瘤CIC标记分子。这是因为分子普遍表达的偶然一致，还是由于CD44因能满足CICs特性要求（例如自我更新、壁龛准备、内皮间充质转移和抗凋亡）而优先表达呢？

CD44 has been implicated as a CIC marker in several malignancies of haematopoietic and epithelial origin. Is this a fortuitous coincidence owing to the widespread expression of the molecule or is CD44 expression advantageous as it fulfils some of the special properties that are displayed by CICs, such as self-renewal, niche preparation, epithelial-mesenchymal transition and resistance to apoptosis?
