In medical studies, doctors and pharmaceutical professionals often need tissue samples to test drugs or other stimuli out and in doing so, learn more about the human body. It comes as no surprise, then, that tissue with a certain disease or other maladies would be of great value to researchers.
This tissue is often subject to advanced testing to see if new breakthrough drugs will be better than their predecessors without risking any living person. It also means there is a lot more room for trial and error, as no person’s quality of life is in direct jeopardy.
One lesser known side of this wonderful process is the need for what is called a “control group.” In every experiment, scientists need a group that is unaltered by experimentation so that they can tell when something has changed.
