Technical Features

The Principle of the µ-Slide Chemotaxis

The μ-Slide Chemotaxis includes three chambers for three parallel assays. One chamber consists of two large reservoirs that are connected by a narrow observation area.

The µ-Slide Chemotaxis was developed to investigate the chemotactical behavior of fast or slow migrating, non-adherent or adherent cells on 2D surfaces or in 3D gel matrices. It is possible to observe the cell migration in linear and stable concentration profiles for more than 48 hours. As gradients are rapidly established, fast migration responses (occurring in less than 30 minutes) can also be measured.

Using the µ-Slide Chemotaxis allows for detailed and defined analysis of the migration behavior of various cell types, such as endothelial cells, fibroblasts, cancer cells, and immune cells.

Gradient Stability in the µ-Slide Chemotaxis

The ibidi μ-Slide Chemotaxis is designed to provide a quick gradient with excellent long-term stability for more than 48 hours. The chamber design is ideally suited for chemotaxis assays with both fast migrating (e.g., leukocytes) and slow migrating cell types (e.g., cancer cells).

In 3D chemotaxis assays using aqueous gels, such as Collagen I or Matrigel, the gradient is stably established and not influenced by the gel in any way.

The reservoirs were filled with 50 nM and 1 nM AlexaFluor 488, respectively. Measurements were performed at five different x-positions, indicated in red. (B) Time-stable linear AlexaFluor 488 concentration profiles were created within the migration chamber, measured by fluorescence correlation spectroscopy.

Application Examples Using the µ-Slide Chemotaxis

Live Cell Imaging of Actin Dynamics in a Chemotactic Gradient

F-actin networks play an important role during cell migration, which can be investigated in detail using chemotactic gradients. Primary dendritic cells were isolated from mice and transfected with the LifeAct Plasmid.

For the chemotaxis assay, cells were seeded on the µ-Slide Chemotaxis and a chemotactic gradient (CCL19) was applied. One day after the transfection, F-actin dynamics in the migrating cells were visualized using live cell imaging.

Chemotaxis of Leukocytes in 3D

Fast leukocytes, such as dendritic cells or T-cells, can be visualized well during chemotaxis when inside gel matrices like collagen. This is especially true when using high-resolution fluorescence microscopy, which shows changes in the cytoskeleton during immune response and 3D interstitial migration.

Chemotaxis Inhibition in Endothelial Cells (HUVEC)

Endothelial cells form the tip of the spear when blood vessels are generated during tumor development. Blocking this chemotaxis-driven mechanism is one of the key goals in anti-angiogenic therapeutic approaches. With the µ-Slide Chemotaxis, endothelial cells can be exposed to compounds that inhibit chemotaxis functionality.

Chemotaxis Inhibition in Endothelial Cells

Distinguishing Chemotaxis and Chemokinesis in Cancer Cells

Chemotaxis, described as the directed motion towards a chemoattractant, can be distinguished from chemokinesis, which is known as an enhanced migration effect.

The µ-Slide Chemotaxis allows for the analysis of both effects, independent of each other (unlike transwell assays). In the example, the chosen chemoattractant induces both chemotaxis and chemokinesis of cancer cells.

Cell-to-Cell Chemotaxis

The ibidi μ-Slide Chemotaxis can additionally be used for cell-to-cell chemotaxis assays. For example, cells brought inside the large reservoirs can be used as a chemoattractant producer.

In the example shown in the figure (Zengel et al., 2011), the cell line FaDu was chosen as a possible source for a chemoattractant. Endothelial cells (HUVEC) were tested for their chemotactic response. HUVEC show a similar chemotaxis effect in direction towards the FaDu cells, which is comparable to the chemotaxis effect towards 10% fetal calf serum as chemoattractant.

Susanne Proksch, Medical Center–University of Freiburg, Freiburg, Germany

"The µ-Slide Chemotaxis made it possible to study stem cell-mediated chemoattraction of tissue cells, which was realized in a co-culture experiment. I was thrilled with the deliberate system and the convenient all-in-one package supplied by ibidi, including training classes and online courses on how to set up the experiment and how to analyze the data, all with perfect individual customer support. From my point of view, the method is pretty fancy and the µ-Slide Chemotaxis system is very sophisticated, allowing for in vivo-like insights into cell behavior for high-impact publications."

"The ibidi µ-Slides Chemotaxis have been the key to my research on lymphocyte chemotaxis. These slides have allowed me to track and visualize directional motility in lymphocytes. The generated chemokine gradients are stable for over 24 hours and the viability of the cells is amazingly good, allowing for measurements of chemotaxis over prolonged time frames.

I am also using the ibidi Gas Incubation and Temperature Control Systems, which are robust and guarantee perfect stability. Very importantly, the product developers at ibidi provide a great support for the implementation of their systems. Thanks to ibidi for developing cell imaging products of such great quality!"
