Abstract

Chemotaxis is an important biological process involved in the development of multicellular organisms, immune response and cancer metastasis. In order to better understand how cells follow chemical cues in their native environments, we recently developed a microfluidics-based chemotaxis device that allows for observation of cells or cell aggregates in 3D networks in response to tunable chemical gradients (Aizel et al., 2017). Here, we describe the methods required for fabrication of this device as well as its use for live imaging experiments and subsequent analysis of imaging data. This device can be adapted to study a number of different cell arrangements and chemical gradients, opening new avenues of research in 3D chemotaxis.
