text: Cell-cell and cell-glycocalyx interactions under flow are important for the
behaviour of circulating cells in blood and lymphatic vessels. However, such interactions
are not well understood due in part to a lack of tools to study them in defined
environments. Here, we develop a versatile in vitro platform for the study of
cell-glycocalyx interactions in well-defined physical and chemical settings under
flow. Our approach is demonstrated with the interaction between hyaluronan (HA,
a key component of the endothelial glycocalyx) and its cell receptor CD44. We
generate HA brushes in situ within a microfluidic device, and demonstrate the
tuning of their physical (thickness and softness) and chemical (density of CD44
binding sites) properties using characterisation with reflection interference
contrast microscopy (RICM) and application of polymer theory. We highlight the
interactions of HA brushes with CD44-displaying beads and cells under flow. Observations
of CD44+ beads on a HA brush with RICM enabled the 3-dimensional trajectories
to be generated, and revealed interactions in the form of stop and go phases with
reduced rolling velocity and reduced distance between the bead and the HA brush,
compared to uncoated beads. Combined RICM and bright-field microscopy of CD44+
AKR1 T-lymphocytes revealed complementary information about the dynamics of cell
rolling and cell morphology, and highlighted the formation of tethers and slings,
as they interacted with a HA brush under flow. This platform can readily incorporate
more complex models of the glycocalyx, and should permit the study of how mechanical
and biochemical factors are orchestrated to enable highly selective blood cell-vessel
wall interactions under flow.
