This paper describes a core-shell hydrogel microfiber consisted of alginate and tetra-arm poly(ethylene glycol) (tetra-PEG) encapsulating rat insulinoma cells using a microfluidic process with a coaxial device and rapid gelation induced by diffusion of two different cross-linkers of barium ion and dithiothreitol (DTT) in the laminar flow (Fig. 1). Microfluidic techniques are able to encapsulate the...
We propose a method for constructing fiber-type three-dimensional (3D) tissue of human iPS-derived cardiomyocytes and quantifying its contractile force in response to the addition of drug. By culturing the cardiomyocytes in micropatterned hydrogel with anchors, we succeeded in fabrication of the fibers with aligned cardiomyocytes and fixation of the fiber edges to the anchors. Since the fiber generated...
