Abstract:

In this study, using biodegradable polymers, nanofiberouse scaffolds were fabricated from the layer-by-layer electrospinning method, including two layer that poly (ε-caprolactone), polyvinylpyrrolidone deposited at first layer and poly (ε-caprolactone), polyvinyl alcohol , β-tricalcium phosphate at latter. After prepration of scaffolds, scanning electron microscopy (SEM), swelling, porosity, mechanical properties and biodegradability behavior in buffered saline phosphate solution were  studied. The results confirmed the bioactivity  and suitable mechanical properties of the layer-by-layer scaffold. The swelling increase with the addition of hydrophilic polymers and reache 811 ± 214 % in the layer-by-layer scaffold, which reveald a significant difference compared to pure PCL. The MTT test on the layer-by-layer scaffold, after 3, 5 and 7 days of rats bone marrow stem cells (rMSC) culture, showed the cell viability of above 80% moreover, cells morphology on the scafold indicated the optimal compatibility of  cells on the scaffold.

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...

Microstereolithography-Based Fabrication of Anatomically Shaped Beta-Tricalcium Phosphate Scaffolds for Bone Tissue Engineering

Porous ceramic scaffolds with shapes matching the bone defects may result in more efficient grafting and healing than the ones with simple geometries. Using computer-assisted microstereolithography (MSTL), we have developed a novel gelcasting indirect MSTL technology and successfully fabricated two scaffolds according to CT images of rabbit femur. Negative resin molds with outer 3D dimensions c...

Electrospun chitosan-graft-poly (ɛ-caprolactone)/poly (ɛ-caprolactone) nanofibrous scaffolds for retinal tissue engineering

A promising therapy for retinal diseases is to employ biodegradable scaffolds to deliver retinal progenitor cells (RPCs) for repairing damaged or diseased retinal tissue. In the present study, cationic chitosan-graft-poly(ɛ-caprolactone)/polycaprolactone (CS-PCL/PCL) hybrid scaffolds were successfully prepared by electrospinning. Characterization of the obtained nanofibrous scaffolds indicated ...

Nanofibrous Scaffolds for Tissue Engineering Applications

The discipline of tissue engineering opens up the ways for repair and regenerate damaged organs and tissues. In the current work biomimetic nanofibrous scaffolds were fabricated by electrospinning. Poly-L-lactic acid (PLLA) was blended with collagen and gelatin to fabricate PLLLA-collagen and PLLA-gelatin fibrous scaffolds respectively. Pure PLLA and gelatin scaffolds served as controls. All th...
