Abstract



Microfluidics for Interrogating Intact-Tumor Biopsies

Albert Folch, Associate Professor of Bioengineering, University of Washington

Cancer remains a major healthcare challenge worldwide. It is now well established that cancer cells constantly interact with fibroblast cells, endothelial cells, immune cells, signaling molecules, and the extracellular matrix in the tumor microenvironment (TME). Present tools to study drug responses and the TME have not kept up with drug testing needs. The number of clinical trials of combination therapies has been climbing at an unsustainable rate, with 3,362 trials launched since 2006 to test PD-1/PD-L1-targeted monoclonal antibodies alone or in combination with other agents. We have developed a microfluidic platform (called Oncoslice) for the delivery of multiple drugs with spatiotemporal control to live tumor biopsies, which retain the TME. We have developed the use of Oncoslice for the delivery of small-molecule cancer drug panels to glioblastoma (GBM) xenograft slices as well as to slices from patient tumors (GBM and colorectal liver metastasis). In addition, we have developed a precision slicing methodology that allows for producing large numbers of cuboidal micro-tissues (“cuboids”) from a single tumor biopsy. We have been able to trap cuboids in arrays of microfluidic traps in a multi-well platform. This work will potentially allow for the high-throughput application of drugs to intact human tumor tissues.
