Enzyme‐Regulated Extended Swelling of Hydrogels for Dehiscence‐Less Tissue Expansions

open access: yesAdvanced Functional Materials, EarlyView.
An interpenetrating hydrogel network with swelling under regulation by enzymatic degradation (INSURED) is fabricated to avoid dehiscence. INSURED remains structurally intact post‐implantation, while HYAL injection enables control over the onset and rate of swelling.

Engineering Highly Cellularized Living Materials via Mechanical Agitation

open access: yesAdvanced Functional Materials, EarlyView.
A mechanical agitation strategy is developed to engineer highly cellularized living materials, achieving cell densities of up to 1 billion cells per milliliter. By precisely tuning properties such as stiffness and toughness in blood clots, the approach is validated in both in vitro and in vivo studies.
