Circulating tumor cells (CTCs) and their clusters are the cellular drivers of metastasis. This study uses microfluidic models mimicking human capillary bifurcations to better understand how these cells interact with capillary beds. Patient CTCs, CTC-derived explant cells, and numerous cancer cell lines shed nuclei-free fragments in a cell size- and bifurcation-dependent manner. These shedding events, which reduces cell sizes up to 61%, facilitate CTC transit through bifurcations. The shed fragme  ...[more]
