Controlling Intestinal Organoid Polarity using Synthetic Dynamic Hydrogels Decorated with Laminin‐Derived IKVAV Peptides

Advanced Healthcare Materials, EarlyView.
Design rules are presented to control intestinal organoid polarity in fully synthetic hydrogels. The laminin‐derived IKVAV sequence is crucial to obtain correct intestinal organoid polarity. Increasing hydrogel dynamics further supports the growth of correctly polarized intestinal organoids, while a bulk level of stiffness (G’ ≈ 0.7 kPa) is crucial to ...

Spatial Patterning of Modular Gelatin‐Peroxide Microspheres in Melt‐Electrowritten Scaffolds Provides Controlled Oxygen Generation and Mitigates Hypoxia and Cytotoxicity

Advanced Healthcare Materials, EarlyView.
A bioassembly approach is described using photo‐crosslinked gelatin‐based microgels containing calcium peroxide (CaO2) to generate oxygen (O2) and enhance cell survival in hypoxic conditions (1% O2). Bioassembly enables spatial patterning of individual CaO2‐laden and mesenchymal stem cell (MSC)‐laden microgels and allows for decoupling and mitigating ...
