Neural Migration and Chemotaxis

During embryonic development, neural progenitor cells undergo a series of complex migration and chemotaxis events to form the different structures of the nervous system, including the brain and spinal cord. Neural progenitor cells originate in the neural tube and undergo radial migration to reach their final destination, where they differentiate into various types of neurons and glial cells. This process is tightly regulated by a variety of molecular cues, including signaling molecules and adhesion molecules, which guide the migrating cells along chemical gradients. For example, the axons of developing neurons are guided by gradients of chemoattractant and chemorepulsive signals that help them navigate toward their appropriate targets (axon guidance).

Migration and chemotaxis also play a role in the immune response of the nervous system and brain repair. After injury or disease, neurons and microglia (which are the primary innate immune cells of the brain), migrate to the site of injury to help repair damaged tissue and restore function (wound healing).

The µ-Slide Chemotaxis and the sticky-Slide Chemotaxis are ideal for analyzing single cell migration in 2D and 3D.

Chemotactic gradients can be easily established in water-based 3D gels, such as Collagen I gels (e.g., rat tail or bovine) because the gel structure does not hinder the formation of a soluble gradient by diffusion (AN 26: Collagen I Gel for 3D Cell Culture).

The ibidi Culture-Inserts with 2 Wells, 3 Wells, or 4 Wells are sticky silicone inserts with a defined cell-free gap for wound healing, migration, 2D invasion assays, and co-cultivation of cells. They are available as individual inserts in a µ-Dish or as 25 pieces for self-insertion. For high-throughput experiments, we provide the Culture-Insert 2 Well 24.


The ibidi Stage Top Incubators provide physiological conditions for live cell imaging during cell migration and chemotaxis assays on every standard inverted microscope. They include CO2 and O2 control as well as actively controlled humidity. They can be used with slides, dishes, or multiwell plates.
