OT:

DMSO is a liquid that you can dissolve a wide variety of compounds in. So when you're testing certain compounds, they'll have low solubility in water (or a similar aqueous solution) so you'll dissolve them in DMSO prior to their addition to the cell media.

Since DMSO is an organic, you use it as the control just to make sure that the effect you're seeing is from the drug, not the organic solvent that you used to dissolve the drug in.
