Most cancers form a solid tumor but some, like leukemia, do not.

大多数肿瘤形成实体瘤，但有些不是实体瘤如白血病。

Unlike many other therapies, bacteria don't target a specific type of cancer, but rather the general characteristics shared by all solid tumors.

不同于其他疗法，细菌并非只针对一种癌细胞，而是以实体瘤的一些共有特征作为靶点。

This really opens up an avenue for having the immune system to attack all kinds of cancers, not just breast cancers, but every kind of solid tumor.

这真的为免疫系统攻击各种癌症开辟了一条途径，不仅仅是乳腺癌，而是每一种实体肿瘤。

An intriguing finding is the observation that MSCs can contribute to the formation of stroma in solid tumors and tumor metastases and that they can deliver therapeutic genes such as interferon and induce tumor regressions.

一项有趣的发现观察到MSCs可以促进实体瘤和转移瘤中基质的形成，并且它们可以运输治疗基因如干扰素并诱导肿瘤消退。
