Spatially Controlled Embedded Bioprinting of Prevascularized Spheroids‐Containing Biopatch Enables Functional Skin Regeneration

Advanced Healthcare Materials, EarlyView.
A spatially controlled embedded bioprinting strategy enables precise engineering of prevascularized multicellular spheroids within skin‐derived dECM bioinks. Optimized spheroid size, composition, and spacing promote vascular maturation, paracrine signaling, and tissue integration, resulting in enhanced angiogenesis, blood perfusion, and functional skin

Advancing Human Skin Equivalents: The Crucial Role of Neurovascular Integration

Advanced Healthcare Materials, EarlyView.
This review discusses the importance of integrating vascular and peripheral nerve systems into human skin equivalents (HSEs) to better recapitulate native skin physiology. Recent advances in vascularized, innervated, and neurovascularized HSEs are highlighted, together with emerging bioengineering strategies, current challenges, and future ...

Self‐Healing Hydrogel‐Enabled Modular Assembly of Bilayered Skin Construct for Hair Follicle Regeneration

Advanced Healthcare Materials, EarlyView.
Self‐healing assembly of two cell‐laden hydrogel layers creates a biomimetic skin construct that restores both dermal and epidermal functions, resulting in accelerated wound healing and enhanced hair follicle regeneration in a full‐thickness skin wound model. ABSTRACT Alopecia remains a pervasive clinical challenge, largely owing to the limited ability

Macrophage–Fibroblast Crosstalk Governs Tumor Mechanics, as Revealed by Spatiotemporal Force Mapping in 3D Spheroids

Advanced Healthcare Materials, EarlyView.
This study shows crosstalk among tumor cells, fibroblasts, and macrophages alters the physical forces inside 3D tumor spheroids. Incorporating deformable microparticles in 3D tumor spheroids, the researchers mapped mechanical stresses spatially and with respect to tumor growth (temporally).
