We are interested in studying how neuron stem cells interact, migrate, and differentiate in 3D biomaterials. Microfluidic techniques permit precise control over and monitoring of the microenvironment a cell experiences.  Soluble chemical gradients are generated within such a device as a stimulating signal, and our protein-based biomaterials can be tailored to provide desired mechanical and surface-bound chemical cues. By analyzing cell responses and tracking cell migration under different conditions, we hope to better understand how nature guides and directs neuron stem cells for tissue repair and regeneration.
