Researchers develop novel 3-D culture system for inflammatory breast cancer
Date:12/8/2012

SAN ANTONIO, TX (December 8, 2012)Inflammatory breast cancer (IBC) is a very rare and aggressive disease that progresses rapidly and is associated with a very low survival rate. To understand how this type of cancer spreads, it's crucial to characterize the interactions between cancer cells and their 3D environment. Researchers at Fox Chase Cancer Center have developed a novel, 3D culture system that mimics the environment surrounding these cancer cells. This model could be used to test new anticancer drugs capable of inhibiting the spread of IBC tumors.

"The tumor microenvironment plays a pivotal role in tumor development and progression, and it also plays a big role in restricting tumorigenesis," says senior study co-investigator Edna Cukierman, PhD, Associate Professor of Cancer Biology at Fox Chase. "So understanding the interactions between the tumor and the environment will help us to come up with new ways to target the tumor." K Alpaugh, a co-author in this collaborative work, will present the study findings at the 2012 CTRC-AACR San Antonio Breast Cancer Symposium on Saturday, December 8, 2012.

For the study, Cukierman, a tumor microenvironment expert, and her colleagues in the lab of Massimo Cristofanilli, MD, Professor at Fox Chase and a leading expert in inflammatory breast cancer, used tumor-associated stromal cells from patients with advanced IBC to build a 3D structure consisting of cell-derived extracellular matrixscaffold that provides structural and biochemical support to cells.

After culturing a plethora of established and patient-derived cancer cells in the stromal 3D system, the researchers categorized them into two groups. While some cells showed a significant increase in proliferation and resembled those seen in aggressive tumors, others were more similar to cells in less-aggressive tumors. These two types of cells modified the extracellular matrix in distinct ways, indicating that there is a dynamic interp
