Article Title: Profiling migration of human monocytes in response to chemotactic and barotactic guidance cues

doi: 10.1016/j.crmeth.2024.100846

Figure Lengend Snippet: A MAP chip for quantitative analysis of immune cell migration characteristics at a single-cell level (A) The MAP chip contains four different sets of microchannels: chemotaxis, chemotactic maze, dual taxis, and distance dual taxis. Monocytes are loaded into the CENTRAL chamber of a primed MAP chip and can migrate through the microchannels into the CHEMOKINE chambers. (B) An experimental pipeline illustrating how human monocytes from different donor groups were isolated, stimulated if applicable, and loaded into the MAP chip primed with either CCL2 or CCL5 chemokine. Cell motility was then tracked at a single-cell resolution using time-lapse imaging. The data were quantified to detail monocyte migration characteristics. Additionally, flow cytometry was performed on the monocytes to quantify specific receptor expression levels.

Figure Lengend Snippet: Monocytes migrate through the path of lower hydraulic resistance regardless of donor age or proinflammatory cytokine stimulation (A) The dual-taxis microchannels contain a chemotactic gradient and varying hydraulic resistances. At the bifurcation of each microchannel, the hydraulic resistance is increased by 6×, 14×, or 51× in the right path compared to the left path. (B) Schematic showing a magnified view of the bifurcation within the 6× hydraulic resistance design. (C) Representative time-lapse confocal microscopy imaging of monocytes (cell membrane, green; nuclei, blue) in the dual-taxis microchannels primed with 100 nM CCL2 chemokine. Scale bar, 10 μm.

Figure Lengend Snippet: Spatial confinement does not dictate the migration of human monocytes toward lower hydraulic resistance paths (A) The distance dual-taxis microchannels contain equal dimensions at the bifurcation and varying distances to a change in width and, consequentially, hydraulic pressure.
