1- Microfluidic devices for cellular tissue encapsulation

Context :
Microfluidic devices are well suited to accurately position cells and tissues, control cell shape and function, and so create highly structured 3D culture microenvironments. Indeed, 3D cell-culture devices promote levels of cell differentiation and tissue organization not possible in conventional 2D culture systems. Unfortunately, most studies on cell and tissue regulation have relied on analysis of cells grown in 2D cell-culture models that partially restrict cell spreading and that fail to reconstitute the in vivo cellular microenvironment.

Objectives & Methods:
We here propose a double-coaxial laminar flow microfluidic device which produces tuned 3D cell-laden structures of various shapes with different mechanical and biochemical properties that may be used as therapeutic vectors notably for the cell transplantation [1].

Results :
We have produced various 3D microfibers (cf. Fig.1) that encapsulate cells and ECM proteins optimally replicating intrinsic functionalities of tissues with a minimal amount of specific biological materials [1]. We aim to highlight those preliminary and promising achievements by optimizing biological and chemical materials used for microfibers and also by implementing innovating fabrication techniques for microfluidic device. These improvements will permit to achieve cell-laden microfibers that exhibit optimal tissue morphologies and functions. We finally intend to realize in vivo investigations developing both safe and dedicated protocols for cell transplantation applications in order to demonstrate the relevance of artificial cell-fibres.
