  • Migration of HaCaT cells on 10 μm micropatterns in the presence of 50 μM blebbistatin. Despite cells migrating into the fibronectin strips, epithelial-bridge formation was markedly inhibited, suggesting that myosin contractility was indeed required for the formation of epithelial bridges.

Focused MDA-MB-231 cells (near the inner wall (top side)) are clearly distinguished from WBCs based on morphology and phase contrast. Few platelets are observed going into the CTC outlet. However, their presence do not interfere during counting using immunofluorescence staining or downstream molecular assay such as PCR. (ME Warkiani et al, Lab on a Chip, 2014).
