Overview

Center Summary

The Cornell Center on the Microenviroment & Metastasis combines expertise in biomedical engineering and clinical research to address and understand the interaction of mechanical forces and chemical cues in cancer metastasis. Our researchers use expertise in fabricating nano- and microfluidic devices to model the tumor environment in three-dimensions. This approach imparts spatial and temporal resolution far greater than obtained by conventional two-dimensional tissue culture models and allows monitoring non-linear responses to a combination of physical, chemical, genetic, and epigenetic stimuli. Our researchers merge these three-dimensional tumor models with advanced imaging techniques to investigate the impact of physicochemical factors in tumor vascularization. Along with these studies, an epigenetic and global transcriptome analysis is underway on the tumor model following various perturbations. This multi-disciplinary approach is yielding quantitative measurements from the highly controlled tumor environment to formulate mathematical models of vascular invasion as well as to generate a better understanding of the signaling pathways that regulate the angiogenic switch.

Projects

Project 1 - Physiochemical Transducers and their Role in Tumor Angiogenesis

Project Leaders: Claudia Fischbach-Teschl (Cornell University) and Vivek Mittal (Weill Cornell Medical Center)

Tumors consist of distinct niches, and cellular crosstalk between these niches enhances tumor angiogenesis and metastasis via the recruitment of bone marrow elements. This project integrates tissue engineering, microfluidics, and mathematical modeling to recreate tumor-like niches and study the underlying extra- and intracellular signaling across multiple length scales. Studies in mouse models complement these physical sciences tools to assess the relevance of the identified signaling to bone marrow progenitor recruitment and metastasis.

Project 2 - Physical and Chemical Cues in Tumor Cell Migration

Project Leaders: Cynthia Reinhart-King (Cornell University) and Paraskevi Giannakakou (Weill Cornell Medical Center)

Metastatic cell migration is intimately linked to the chemical and mechanical properties of the microenvironment. This project will deconvolve these contributions. It will apply quantitative and enabling new methodologies from the physical sciences to study the mechanisms underlying the spatial and temporal regulation of metastatic cell migration in 3D.

Physical and Chemical Cues in Tumor Cell Migration

Project 3 - Adhesion of Tumor Cells in the Vascular Microenvironment

Project Leaders: Michael R. King (Cornell University) and David Nanus (Weill Cornell Medical Center)

This project is focused on understanding the fundamental physical mechanisms of circulating tumor cell adhesion to inflamed endothelium under flow, as a critical step in the hematologic spread of metastatic cancers. It will address how the vascular microenvironment controls the recruitment and extravasation of circulating tumor cells. Micro/nanofabrication, fluid mechanics, and surface chemistry techniques will be used to accurately recreate elements of the complex in vivo microenvironment.

Cores

Core 1 - Fabrication Core

Core Leader: Graham Kerslick (Cornell University)

Nanobiotechnology center shared research facilities integrate nano-and microfabrication capabilities with biochemical processing and analysis tools in an environment designed to enhance interdisciplinary research. Facility staff members offer extensive support in problem solving throughout a research project and training in the use of tools and equipment that may be unfamiliar to them. Special workshops will be available to the PS-OC community, in microfluidic device design and fabrications, scanned probe microscopy, and surface characterization techniques for biomaterials.

The Cornell NanoScale Science & Technology Facility (CNF) is a national user facility that supports a broad range of capabilities including fabrication, synthesis, computation, characterization, and integration. These enable users to build structures, devices, and systems from atomic to complex length-scales. The CNF has dedicated Life Sciences liaison staff who give process support to users with biology-based projects and aids users with finding collaborators; this will enable PS-OC researchers to apply the tools of nano-and microfabrication to create systems to study aspects of cancer in a precise manner.

Core 2 - Selected Cell Epigenomic Analysis Core

Core Leaders: Harold Craighead (Cornell University) and Ari Melnick (Weill Cornell Medical Center)

The Core will develop processes and devices to rapidly evaluate the molecular state of a few selected cells and work toward analysis of individual cells. The Core will enable PC-OC scientists to understand the distribution of properties and to then consider the consequences of this heterogeneity in the context of various microenvironments. Services are offered in close collaboration with the CLC sequencing, microarrays and informatics cores.
