The term in vivo is Latin for within the living. It refers to tests, experiments, and procedures that researchers perform in, or on, a whole living organism. The term pharmacology is a branch of science that deals with the study of drugs and their actions on living systems. The in vivo pharmacology studies we perform at Certis involve growing an individual’s unique type of cancer in very specialized, immunocompromised research mice, then testing tumor response to multiple therapeutic options simultaneously. The information we gathered can help your oncologist determine the most effective cancer treatment for you.
