Fabrication of chitosan microparticles loaded in chitosan and poly(vinyl alcohol) scaffolds for tissue engineering application

Chitosan microparticles as injectable scaffolds for tissue engineering.

The use of chitosan microparticles as injectable carriers for cell transplantation represents a promising alternative to avoid the drawbacks of the implantation of other forms of three-dimensional (3D) scaffolds seeded with cells. In this study, a 3D construct is obtained in vitro by combining chitosan microparticles crosslinked with genipin and goat bone marrow stromal cells (GBMCs). Cell viab...

Cytocompatibility of Chitosan and Collagen-Chitosan Scaffolds for Tissue Engineering

In this work, chitosan and collagen-chitosan porous scaffolds were produced by the freeze drying method and characterized as potential skin substitutes. Their beneficial effects on soft tissues justify the choice of both collagen and chitosan. Samples were characterized using scanning electron microscope, Fourier Transform InfraRed Spectroscopy (FTIR) and thermogravimetry (TG). The in vitro cyt...

Fabrication of Chitosan/Poly (vinyl alcohol)/Carbon Nanotube/Bioactive Glass Nanocomposite Scaffolds for Neural Tissue Engineering

Tissue engineering in medical engineering has been always raised and expanded for the repair and replacement of damaged or destroyed tissues and organs operations. Nerve regeneration is a precious treatment for human health because it is directly related to the quality of human life. It is quite clear that human central nervous system (CNS) in adults is unable to repair itself after being damag...

Emulsified Chitosan-plga Scaffolds for Tissue Engineering

design and fabrication of biodegradable porous chitosan/gelatin/tricalcium phosphate hybrid scaffolds for tissue engineering

in this study, based on a biomimetic approach, novel 3d biodegradable porous hybrid scaffolds consisting of chitosan, gelatin, and tricalcium phosphate were developed for bone and cartilage tissue engineering. macroporous chitosan/ gelatin/β-tcp scaffolds were prepared through the process of freeze-gelation/solid-liquid phase separation. the results showed that the prepared scaffolds are highly...
