Piezoelectric Nanocomposite Hydrogel for Wireless Neural Stimulation and Tissue Augmentation

Advanced NanoBiomed Research, EarlyView.
A cell/tissue supporting piezoelectric hydrogel system (PZ‐gel) that incorporates ferroelectric, pyroelectric, and piezoelectric ceramic material barium titanate into an alginate/carboxymethyl chitosan hydrogel. The PZ‐gel can be sonoactivated for wireless neural cell and tissue stimulation, with the potential to be used as a stimulatory cell substrate

Development of vascularized nerve scaffold using perfusion-decellularization and recellularization [PDF]

, 2020
Introduction Vascularized nerve grafts (VNG) may offer an advantage in peripheral nerve regeneration by avoiding ischemic damage and central necrosis observed in non-VNG, particularly for the treatment of large and long nerve defects.

Fundamentals, Advances, and Applications of Electrospun Nanofibrous 3D Materials

Journal of Applied Polymer Science, EarlyView.
Three‐dimensional electrospun nanofibrous systems offer unique properties and microenvironments. These properties are determined by the fabrication strategies employed and can be adjusted by the incorporation of functional additives to achieve multifunctionality for specific applications. The applications range from the biomedical to the environmental,

Decalcified and Decellularized Bone Conduits for Peripheral Nerve Regeneration: A Comparative In Vivo Study Using Rat Femur and Chicken Ulna Conduits. [PDF]

Brain Behav
ABSTRACT Purpose: Peripheral nerve injuries (PNIs) pose a major clinical challenge, especially when nerve gaps exceed 5 mm and spontaneous regeneration is inadequate. This study aimed to evaluate the regenerative potential of novel bone‐derived nerve guidance conduits (NGCs) fabricated from rat femoral diaphysis and chicken ulna as alternatives to ...

Characterization of the extracellular matrix from human and dog umbilical cords

The Anatomical Record, EarlyView.
Abstract The extracellular matrix is important for maintaining tissue morphogenesis and homeostasis; it can also be used as a biomaterial for the production of biological scaffolds. Particularly, the umbilical cord has shown potential in the production of scaffolds for small‐diameter vessels.
