3D printing cancer tumors
Date:4/25/2014

mperature of the nozzle and using a hearty strain of cancer cells," Sun said. "We chose the Hela cell, which is a robust form of cervical cancer that has been used in research for many years. Because of this, we had a good idea as to how it would behave under certain conditions. This allowed us to control the variables of the extrusion process until we were able to successfully create a model."

Sun's team plans to continue its research in hopes of creating tumors that are even more similar to those that grow in the body. They will work to print tumors composed of multiple different cells a trait often found in those removed from cancer patients. In addition, the group is working on ways to attach the models to tissues and vasculature that they've printed, which would recreate the way tumors grow in their bodily habitat.

"We will try to understand the cell-cell and cell-substrate communication and immune responses for the printed tumor-like models," Sun said. "Our goal is to take this tumor-like model and make it into a more of an in vivo simulation. And to apply it to study the development, invasion and metastasis of cancer, to test the efficacy and safety of new cancer drugs, as well as the specific therapy for individual cancer patient."
