Cell Fiber Technology For 3D Tissue-on-a-Chip Application

Shoji Takeuchi, Professor and Director, The University of Tokyo

The talk describes a 3D cell culture method using core-shell hydrogel microfibers (cell fibers). The core is filled with cells and ECM proteins, and the shell is composed of calcium alginate. Since the core diameter is about 100 microns, oxygen and nutrients can be diffused into the central area of the 3D tissue; therefore this culture system allows us to culture the tissue for a long period without central necrosis. Using this culture system, fiber-based tissues such as blood vessels, nerves, and muscles can be formed with in the core. Here, I will discuss the application of the cell fiber technology for various tissue-on-a-chip studies including cardiac tissue, neuro-muscular junctions, and vascularized skin etc.
