Core Tip
Core tip: The pluripotent nature of embryonic stem cells (ESCs) makes them an ideal source for cell-based therapeutics and regenerative medicine. Efficient and reproducible expansion of ESCs ex vivo is critical for high quality cells for translational applications. However, propagation of ESCs is technically challenging, and often leads to differentiation due to inefficient two-dimensional culture techniques in vitro. To mimic the three-dimensional microenvironment in vivo, self-assembling scaffolds made from thiol-functionalized dextran and polyethylene glycol tetra-acrylate were designed to encapsulate and propagate mouse ESCs. This culture system is simple, robust, efficient and reproducible, permitting long-term maintenance of ESCs without routine passaging and manipulation.
