Chitosan-based scaffolds for bone tissue engineering

Scaffolds based bone tissue engineering: the role of chitosan.

As life expectancy increases, malfunction or loss of tissue caused by injury or disease leads to reduced quality of life in many patients at significant socioeconomic cost. Even though major progress has been made in the field of bone tissue engineering, present therapies, such as bone grafts, still have limitations. Current research on biodegradable polymers is emerging, combining these struct...

Aligned and random nanofibrous nanocomposite scaffolds for bone tissue engineering

Aligned and random nanocomposite nanofibrous scaffolds were electrospun from polycaprolactone (PCL), poly (vinyl alcohol) (PVA) and hydroxyapatite nanoparticles (nHA). The morphology and mechanical characteristics of the nanofibers were evaluated using scanning electron microscopy and tensile testing, respectively. Scanning electron microscopy revealed fibers with an average diameter of 123 ± 3...

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...

A Review on Commonly Used Scaffolds in Tissue Engineering for Bone Tissue Regeneration

Introduction: Bone is one of the tissues that have a true potential for regeneration. However, sometimes the bone defects are so outsized that there is no chance of bone self-repair and restoration or the damage is such that it is not possible to repair with medical or surgical interventions. In these situations, bone grafts are the treatment of choice, but due to several obstacles, including l...
