This meant that in a day's work, I could really only test five or six different experimental conditions to see how the cells responded.

这意味着在一天工作中，我际上只能测试五六个不同条件来观察细胞是如何响应。

As such, we can study cells grown in special dishes that allow us to test hundreds of experimental conditions at a time.

因此，我们可以研究在特殊培养皿中生长细胞，这些培养皿允许我们一次测试数百种条件。
