Live-cell whole tissue models reveal sources of dynamic signaling heterogeneity and single cell drug response variation in the metastatic niche

Osteosarcoma Webinar Series: Alexander Davies, DVM, PhD joins us on OsteoBites to discuss his work which is focused on dynamic tumor-microenvironment signaling cross-talk, signal integration, and the development of 3D organotypic and tissue models to study these interactions using live-cell microscopy techniques. Results from studies in the Davies Lab demonstrate the utility of a novel dynamic live-cell tissue model, the lungSITE model, to quantitatively measure and understand tumor signaling dynamics and behaviors within the context of the lung metastatic niche. Data obtained from this model provided new insights into how spatial position and temporal response influence signaling dynamics, specifically in osteosarcoma lung metastasis, to create intratumoral signaling heterogeneity and consequent single-cell drug response variation. Dr. Alexander Davies graduated with a Ph.D. in Biochemistry and Molecular Biology and a D.V.M., with an interest in comparative oncology, from the University of California, Davis. He then completed a post-doctoral fellowship in cancer biology at Lawrence Berkeley National Laboratory before joining The Ohio State University as faculty in the Department of Veterinary Biosciences. While at OSU he was a member of the Comprehensive Cancer Center and faculty in the Cancer Biology and Cancer Engineering programs. Currently, Dr. Davies is an Assistant Professor at the Knight Cancer Institute within the Division of Oncological Sciences and Cancer Early Detection Advanced Research Center (CEDAR) where his work focuses on dynamic tumor-microenvironment signaling cross-talk, signal integration, and the development of 3D organotypic and tissue models to study these interactions using live-cell microscopy techniques.
