3D Bioprinting‐Assisted Engineering of Stem Cell‐Laden Hybrid Biopatches With Distinct Geometric Patterns Considering the Mechanical Characteristics of Regular and Irregular Connective Tissues

Advanced Healthcare Materials, EarlyView.
A hybrid biopatch platform integrating 3D printed polymeric patterns with stem cell‐laden collagen bioinks is developed to mimic the mechanical properties of connective tissues. By tailoring geometric architectures, the constructs replicate anisotropic or isotropic mechanics, enhancing tissue‐specific regeneration.

Weight Cycling Deregulates Eating Behavior in Mice via the Induction of Durable Gut Dysbiosis

Advanced Science, EarlyView.
Weight cycling in Humans is suspected to dysregulate eating behavior. Mice submitted to body weight cycling by alternating western‐type and regular chow diets display increased hedonic appetite when exposed to a palatable diet, reminiscent of binge‐eating episodes.
