Tissue engineering and regenerative medicine involve many different artificial and biologic
materials, frequently integrated in composite scaffolds, which can be repopulated with …

Tissue engineering (TE) has provided promising strategies for regenerating tissue defects,
but few TE approaches have been translated for clinical applications. One major barrier in …

Shape memory polymers (SMPs) can be triggered by an external stimulus to realize the
shape changing from temporary shape to its original shape. Due to its biodegradability, easy …

As a kind of medical treatment device, shape memory tracheal stent has a good application
prospect. The biodegradable stent can effectively reduce the damage to patients and …

OBJECTIVES Currently, most of the artificial airway organs still require scaffolds; however,
such scaffolds exhibit several limitations. Alternatively, the use of an autologous artificial …

In recent years, scaffold‐free bio‐3D printing using cell aggregates (spheroids) as “bio‐inks”
has attracted increasing attention as a method for 3D cell construction. Bio‐3D printing uses …

Patients with large tracheal lesions unsuitable for conventional endoscopic or open
operations may require a tracheal replacement but there is no present consensus of how …

The lack of a biomimetic tracheal substitute featured with cartilage ring/vascularized
connective tissue alternate structure (CVCAS) has significantly retarded a clinical …

Biomedical implants have recently shown excellent application potential in tissue repair and
replacement. Applying three-dimensional (3D) printing to implant scaffold fabrication can …

Extensive circumferential tracheal defects remain a major challenging problem in the field of
tracheal reconstruction. In this study, a tissue-engineered tracheal graft based on three …
