Abstract

Current animal and 2‐D cell culture models employed in metastasis research and drug discovery remain poor mimics of human cancer physiology. Here we describe a “metastasis‐on‐a‐chip” system allowing real time tracking of fluorescent colon cancer cells migrating from hydrogel‐fabricated gut constructs to downstream liver constructs within a circulatory fluidic device system that responds to environmental manipulation and drug treatment. Devices consist of two chambers in which gut and liver constructs are housed independently, but are connected in series via circulating fluid flow. Constructs were biofabricated with a hyaluronic acid‐based hydrogel system, capable of a variety of customizations, inside of which representative host tissue cells were suspended and metastatic colon carcinoma tumor foci were created. The host tissue of the constructs expressed normal epithelial markers, which the tumor foci failed to express. Instead, tumor regions lost membrane‐bound adhesion markers, and expressed mesenchymal and proliferative markers, suggesting a metastatic phenotype. Metastatic tumor foci grew in size, eventually disseminating from the intestine construct and entering circulation, subsequently reaching in the liver construct, thus mimicking some of the migratory events observed during metastasis. Lastly, we demonstrated the ability to manipulate the system, including chemically modulating the hydrogel system mechanical properties and administering chemotherapeutic agents, and evaluated the effects of these parameters on invasive tumor migration. These results describe the capability of this early stage metastasis‐on‐a‐chip system to model several important characteristics of human metastasis, thereby demonstrating the potential of the platform for making meaningful advances in cancer investigation and drug discovery.

  • Skardal's group demonstrated a 2-organoid metastasis-on-a-chip platform in which CRC cells from colon organoids diffuse into circulation and settle on downstream liver organoids.

    “Skardal’s group demonstrated the utility of a 2-organoid metastasis-on-a-chip (MOC) platform224. By using microfluidics to provide circulating flow through the organoid system, tumor cells grow in the primary focus and enter the circulation, with the result that CRC cells of the colon organoids diffuse into the circulation, and then the transferred cells settle on the downstream liver organoids.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
