Schematic illustration of the core-shell microfiber culture system for human induced pluripotent stem (iPS) cells. (A) An illustration of the double co-axial laminar flow microfluidic device used for the formation of the human iPS cell-laden core-shell hydrogel microfiber. (B) The cells encapsulated within the core-shell microfibers proliferate and form cell aggregations with uniform thickness by expanding along the microfiber.
