Dynamic Three-dimensional Micropatterned Coculture Using Photocurable and Chemically Degradable Hydrogels for Stem Cell Differentiation

Abstract

We report the spatiotemporal control of a 3D coculture by combining photocurable and chemically degradable hydrogels for coculture of embryonic stem (ES) cells with HepG2 cells. ES cells were encapsulated in micropatterned photocurable poly(ethylene glycol) (PEG) hydrogels. The cell-laden PEG hydrogels were then encapsulated in calcium-alginate (Ca-Alg… (More)
