This research focuses on altering cell morphology of invasive and non-invasive cancer cells through extracellular molding techniques. The study aims to investigate how changes in cell morphology affect cell behavior and potential applications in medical technologies such as implantology and cancer treatment.

Extracellular Molding of Invasive and Non-invasive Cancer Cells Elizabeth Smith Mentor: Brandon Lutz Advisor: Dr. Michael Cho Program Director: Dr. Andreas Linninger RET, University of Illinois-Chicago NSF CBET EEC-0743068 June 30, 2011
Background 1) Cells have different morphologies NCM460 SW620 Non-Invasive Invasive Non-Invasive Invasive Breast Cancers Colon Cancers
Osteocyte hMSC Adipocyte Background 2) Cells respond to extracellular topography Substrate topography differences Substrate rigidity differences
Goals • Current • Provide a microscale mold of differing cell morphology to alter the morphology of the seeded cells • Future • Determine if the change in morphology leads to change in cell behavior
