In human vascular anatomy, blood flows from the heart to organs and tissues through a
hierarchical vascular tree, comprising large arteries that branch into arterioles and further …

Clinically, large diameter artery defects (diameter larger than 6 mm) can be substituted by
unbiodegradable polymers, such as polytetrafluoroethylene. There are many problems in …

Abstract 3D printing of high-strength hydrogel remains a great challenge owing to trade-off
between strength and printability. Herein, a zwitterionic strategy was proposed through …

Graft-host mechanical mismatch has been a longstanding issue in clinical applications of
synthetic scaffolds for soft tissue regeneration. Although numerous efforts have been …

Conspectus Hydrogels are high-water-content soft materials with widely tunable
physicochemical properties, resembling soft tissues. Tremendous progress in engineering …

Wound healing and tissue repair are recognized as basic human health problems
worldwide. Attempts to accelerate the reparative process are focused on developing …

Many hydrogel patches are developed to solve the pervasive and severe challenge of
complex wound healing, while most of them still lack satisfactory controllability and …

Advances in bioprinting have enabled the fabrication of complex tissue constructs with high
speed and resolution. However, there remains significant structural and biological …

While there has been considerable success in the three-dimensional bioprinting of relatively
large standalone filamentous tissues, the fabrication of solid fibers with ultrafine diameters or …

Volumetric printing, an emerging additive manufacturing technique, builds objects with
enhanced printing speed and surface quality by forgoing the stepwise ink-renewal step …
