Fold Walker: An Origami‐Inspired Quadruped Robot for Multipattern Locomotion and Object Grasping

Advanced Robotics Research, EarlyView.
This article presents Fold Walker, an origami‐inspired quadruped robot capable of multipattern locomotion and object grasping. With each leg featuring two rotational folds, the robot can transform from a flat 2D configuration into complex 3D poses. Furthermore, its trunk and legs can be one‐shot 3D printed as a unified structure, greatly simplifying ...

Accurate Delivery of Mesenchymal Stem Cell Spheroids With Platelet‐Rich Fibrin Shield: Enhancing Survival and Repair Functions of Sp‐MSCs in Diabetic Wound Healing

Advanced Science, EarlyView.
Autologous plasma‐derived platelet‐rich fibrin (PRF) is prepared as a protective shield for mesenchymal stem cell spheroids (Sp‐MSCs). PRF forms a fibrin shield to protect Sp‐MSCs from the oxidative stress environment. The nutrients in PRF, particularly the α‐granules, can enhance the repair function of Sp‐MSCs.

Inhibition and Rescue of Hyperglycemia‐Induced Cellular Senescence by Mitochondrial Transfer from Enucleated Mesenchymal Stem Cell‐Derived Microvesicles for Chronic Wound Healing

Advanced Science, EarlyView.
This study develops enucleated MSC‐derived microvesicles (Mito@euMVs) to deliver functional mitochondria for optimizing wound repair. By efficiently encapsulating mitochondria, Mito@euMVs rejuvenate hyperglycemia‐induced senescent fibroblasts and HUVECs. Using PVA microneedle patches, the therapeutic efficacy of Mito@euMVs is validated in diabetic rats
