Microscopically Adaptable Bioink Guide Cell Compartmentalization toward Morphogenesis of a Functional Vasculature‐Like System

open access: yesAdvanced Healthcare Materials, EarlyView.
Contractile vasculatures are fabricated through a one‐step bioprinting strategy. The adaptable microenvironment provided by ECM‐mimicking bioink triggers cell sorting and compartmentalization of endothelial cells and vascular smooth muscle cells toward a histological configuration by focal adhesion kinase‐mediated upregulation of cell adhesion and ...

Uniting 4D Printing and Melt Electrowriting for the Enhancement of Regenerative Small Diameter Vascular Grafts

open access: yesAdvanced Healthcare Materials, EarlyView.
A hybrid 4D printing strategy enables the fabrication of shape‐morphing, mechanically reinforced tubular constructs for vascular tissue engineering. By combining alginate‐methylcellulose hydrogels with melt electrowritten polycaprolactone fibers and protein‐based functionalization, this platform supports spatially organized co‐cultures of fibroblasts ...

Reconstruction of intercalary bone defect after resection of malignant bone tumor

open access: yesJournal of Orthopaedic Surgery, 2019
Due to accurate preoperative imaging techniques, early diagnosis and effective chemotherapy, many tumors arising in the metaphyseo-diaphyseal regions of long bones can be segmentally resected with joint preservation.

Granular Hydrogels as Modular Biomaterials: From Structural Design to Biological Responses

open access: yesAdvanced Healthcare Materials, EarlyView.
Granular hydrogels are now emerging as promising biomaterials due to their inherent microporousity, injectability, and modularity. They have shown improvements in cell viability and migration, cellular/tissue infiltration, host tissue integration, mitigated foreign body response, and tissue regeneration.

Modification of free vascularized fibular graft and its use in upper limb injuries

open access: yesActa Médica del Centro, 2013
The restoration with conventional osteogenic contributions is unpredictable with regard to major defects because it integrates as it consolidates their ends as a fracture. In this work, innovations in free vascularized fibular graft were made, one of the

Beyond Bioactive Glass Composition: Using Morphology to Improve in Vitro and in Vivo Performance

open access: yesAdvanced Healthcare Materials, EarlyView.
Bioactive glasses can easily be shaped into granules, spheres, discs, fibers, or three‐dimensional scaffolds. The resulting morphology not only affects handling properties; it has a direct influence on various glass properties, including results of acellular immersion experiments or in vitro studies with cells or bacteria, but also on in vivo ...
