Abstract

Cancer metastases arise following extravasation of circulating tumor cells with certain tumors exhibiting high organ specificity. Here, we developed a 3D microfluidic model to analyze the specificity of human breast cancer metastases to bone, recreating a vascularized osteo-cell conditioned microenvironment with human osteo-differentiated bone marrow-derived mesenchymal stem cells and endothelial cells. The tri-culture system allowed us to study the transendothelial migration of highly metastatic breast cancer cells and to monitor their behavior within the bone-like matrix. Extravasation, quantified 24 h after cancer cell injection, was significantly higher in the osteo-cell conditioned microenvironment compared to collagen gel-only matrices (77.5 ± 3.7% vs. 37.6 ± 7.3%), and the migration distance was also significantly greater (50.8 ± 6.2 μm vs. 31.8 ± 5.0 μm). Extravasated cells proliferated to form micrometastases of various sizes containing 4 to more than 60 cells by day 5. We demonstrated that the breast cancer cell receptor CXCR2 and the bone-secreted chemokine CXCL5 play a major role in the extravasation process, influencing extravasation rate and traveled distance. Our study provides novel 3D in vitro quantitative data on extravasation and micrometastasis generation of breast cancer cells within a bone-like microenvironment and demonstrates the potential value of microfluidic systems to better understand cancer biology and screen for new therapeutics.

  • These microfluidic systems enable continuous delivery of oxygen, nutrients, and therapeutic agents while introducing shear stress and directional mass transport, allowing investigation of flow-regulated processes within a tumor-relevant architecture.

    “These systems enable continuous delivery of oxygen, nutrients, and therapeutic agents while introducing shear stress and directional mass transport, thereby allowing the investigation of flow-regulated processes within a tumor-relevant architecture [224,225,226,227,228].”

  • Different cancer cells (lung, breast, melanoma) flowed through the vascular channel disrupted the integrity of the BBB and extravasated, with the exception of liver cancer cells.

    “A compartmental channel model was used to establish a blood-brain barrier (BBB) [74]; different cancer cells (lung, breast, melanoma) flowed through the vascular channel and were found to disrupt the integrity of the BBB and extravasate, with the exception of liver cancer cells.”
  • Breast cancer cells introduced into the vascular channel transmigrated across an endothelial monolayer into the osteo-cell compartment in a vascularized osteo-cell environment.

    “Breast cancer cells were introduced into the vascular channel, which led to cancer cell transmigration across an endothelial monolayer into the osteo-cell compartment.”
  • Regulation of the cancer cell surface receptor CXCR2 and bone-secreted chemokine CXCL5 significantly altered the extravasation rate.

    “Regulation of the cancer cell surface receptor CXCR2 and bonesecreted chemokine CXCL5 significantly altered the extravasation rate.”

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.
