Engineered and Instrumented Three-Dimensional Tumor-Immune Model System

Elizabeth Wheeler | 19-SI-003

Executive Summary

We will develop a bioprinted, ex vivo, human-relevant, three-dimensional cancerous tumor model that enables spatio-temporal control and measurement of multiple tissue, cellular, and molecular components that drive tumor growth. We will study the effect of the immune system and drugs to modulate tumor microenvironment, growth, and regression to gain data to calibrate computational models, predictions, and personalized therapeutics.
