Chitosan microparticles as injectable scaffolds for tissue engineering

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...

Emulsified Chitosan-plga Scaffolds for Tissue Engineering

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...

Electrically Conductive Chitosan/Carbon Scaffolds for Cardiac Tissue Engineering

In this work, carbon nanofibers were used as doping material to develop a highly conductive chitosan-based composite. Scaffolds based on chitosan only and chitosan/carbon composites were prepared by precipitation. Carbon nanofibers were homogeneously dispersed throughout the chitosan matrix, and the composite scaffold was highly porous with fully interconnected pores. Chitosan/carbon scaffolds ...

Characterization of Chitosan Based Hybrid Nanofiber Scaffolds for Tissue Engineering

Polymeric nanofibers that mimic the structure and function of the natural extracellular matrix (ECM) are of great interest in tissue engineering as scaffolding materials to restore, maintain or improve the function of human tissues. Electrospinning has been recently developed as an effective technique for nanofiber fabrication. In our study, the electropsinning method is used to create hybrid n...
