Those studies were done in cancer cells grown in the lab, not in living animals (in vivo).

那些试验都是在实验室生长的癌细胞，而非活的动物（体内）进行的。

In another called in vivo desensitization, they are exposed, while awake, to what may be haunting them in their sleep.

在另一个被称为体内脱敏现象中，在清醒状态下，他们被暴露在他们睡梦中缠扰着他们的东西前。

The results also show that the proteins would be absorbed by the body, allowing the in vivo antihypertensive activity to occur.

结果还指出，蛋白质会被人体吸收，使抗高压的活动在体内发生。

Many of these deaths could be prevented through the development of in vitro models of human cells and tissues that better mimic in vivo environments.

通过建立能够更好地模拟体内环境的人类细胞和组织的体外模型，能防止许多这样的死亡。

The Purdue scaffold looks like a very interesting approach—it's certainly an advance—but until it's been tested in vivo, it's difficult to comment further.

普渡的支架看起来是个非常有趣的方法——这肯定是一个进步——但是，在进行体内测试之前，很难进一步评判。
