Microfluidic Device Mimics Tumor Microenvironment, Helps Drug Discovery Efforts

One of the challenges that cancer researchers face in designing new antitumor agents is that of predicting how drug molecules will behave in the complex microenvironment that surrounds a tumor. In particular, tumors create all sorts of chemical and physical barriers that limit how much drug is able to enter a tumor, let alone reach cells deep within a tumor. Now, Neil Forbes, Ph.D., and his colleagues at the University of Massachusetts have built a microfluidic device that can mimic these chemical and physical barriers, providing researchers with a new screening tool that may help with the design of more effective anticancer drugs.
