Before the clincial trials, drugs are tested in the laboratory. The laboratory trials are not trials on people. What is the drug tested on in these laboratory trials?

Explanation:

Before the drugs can be tested on humans they have to be tested using a few other methods first. Firstly they have to complete computer model tests and human cells grown from stem cells.
