text: Directed migration of cells relies on their ability to sense directional guidance
cues and to interact with pericellular structures in order to transduce contractile
cytoskeletal- into mechanical forces. These biomechanical processes depend highly
on microenvironmental factors such as exposure to 2D surfaces or 3D matrices.
In vivo, the majority of cells are exposed to 3D environments. Data on 3D cell
migration are mostly derived from intravital microscopy or collagen-based in vitro
assays. Both approaches offer only limited controlla-bility of experimental conditions.
Here, we developed an automated microfluidic system that allows positioning of
cells in 3D microenvironments containing highly controlled diffusion-based chemokine
gradients. Tracking migration in such gradients was feasible in real time at the
single cell level. Moreover, the setup allowed on-chip immunocytochemistry and
thus linking of functional with phenotypical properties in individual cells. Spatially
defined retrieval of cells from the device allows down-stream off-chip analysis.
Using dendritic cells as a model, our setup specifically allowed us for the first
time to quantitate key migration characteristics of cells exposed to identical
gradients of the chemokine CCL19 yet placed on 2D vs in 3D environments. Migration
properties between 2D and 3D migration were distinct. Morphological features of
cells migrating in an in vitro 3D environment were similar to those of cells migrating
in animal tissues, but different from cells migrating on a surface. Our system
thus offers a highly controllable in vitro-mimic of a 3D environment that cells
traffic in vivo.
