New Synthetic Tumor Environments Make Cancer Research More Realistic

August 31, 2015 10:42 am | by University of Illinois | Comments

Tumors are notoriously difficult to study in their natural habitat – body tissues – but a new synthetic tissue environment may give cancer researchers the next-best look at tumor growth and behavior. Researchers have developed a new technique to create a cell habitat of squishy fluids, called hydrogels, which can realistically and quickly recreate microenvironments found across biology.
