PNIPAAm-based biohybrid injectable hydrogel for cardiac tissue engineering

Acta Biomaterialia, 2016
Injectable biomaterials offer a non-invasive approach to deliver cells into the myocardial infarct region to maintain a high level of cell retention and viability and initiate the regeneration process. However, previously developed injectable matrices often suffer from low bioactivity or poor mechanical properties. To address this need, we introduced a

Reconfiguration of Multiphase Coacervate Droplets Into Self-Regulated Nested Artificial Cells. [PDF]

Angew Chem Int Ed Engl
Living cells advance functionality through spatiotemporal sub‐compartmentalization and internal organization. Herein, we develop a self‐regulated artificial cell by transforming a membrane‐less multiphase coacervate droplet (MCD) into a membranized, structurally reinforced nested coacervate vesicle (NCV).
