Efficient extravasation of tumor-repopulating cells depends on cell deformability
Cancer metastasis is the most deadly stage in cancer progression. Despite significant efforts over the past decades, it remains elusive why only a very small fraction of cancer cells is able to generate micrometastasis and metastatic colonization. Recently we have shown that tumor-repopulating cells (TRCs), a highly tumorigenic subpopulation of mouse melanoma cells, can be selected by being cul...
متن کاملEfficient cross-presentation depends on autophagy in tumor cells.
Cross-presentation of antigens is critical for the induction of adaptive immunity against tumor cells and infectious pathogens. Currently, it is not known how cross-presentation of tumor antigens is regulated by autophagy. Using both HEK 293T cells that expressed the model antigen OVA and melanoma cells as antigen donors, we show that macroautophagy in tumor cells is essential for cross-present...
متن کاملDeformability of Tumor Cells versus Blood Cells
The potential for circulating tumor cells (CTCs) to elucidate the process of cancer metastasis and inform clinical decision-making has made their isolation of great importance. However, CTCs are rare in the blood, and universal properties with which to identify them remain elusive. As technological advancements have made single-cell deformability measurements increasingly routine, the assessmen...
متن کاملVisualizing extravasation dynamics of metastatic tumor cells.
Little is known about how metastatic cancer cells arrest in small capillaries and traverse the vascular wall during extravasation in vivo. Using real-time intravital imaging of human tumor cells transplanted into transparent zebrafish, we show here that extravasation of cancer cells is a highly dynamic process that involves the modulation of tumor cell adhesion to the endothelium and intravascu...
متن کاملIn Vitro Model of Tumor Cell Extravasation
Tumor cells that disseminate from the primary tumor and survive the vascular system can eventually extravasate across the endothelium to metastasize at a secondary site. In this study, we developed a microfluidic system to mimic tumor cell extravasation where cancer cells can transmigrate across an endothelial monolayer into a hydrogel that models the extracellular space. The experimental proto...
