||Abstract:"...[investigators] developed a microfluidic device that is simple to operate and allows for precise and robust measurements of chemotaxis speed and persistence characteristics at single-cell resolution. Using this assay, [they] established a reference set of migration speed values for neutrophils from healthy subjects."
||P.5 left column:"In additional control experiments, in the absence of fMLP [N-Formylmethionyl-leucyl-phenylalanine] chemokine, neutrophils did not migrate through the side channels of the device. Furthermore, when a sample of neutrophils was diluted ten-fold, the measured average migration speed was unchanged (17±6 µm/min and 18±4 µm/min, p = 0.3), suggesting that migration speed was independent of the concentration of neutrophils in the device."
