OBJECTIVE The bioscaffold can be used in tissue engineering and regenerative medicine. The scaffolds used in tissue engineering must have high porosity to facilitate accelerated angiogenesis for feeding cells and repelling cell waste outside the scaffold. In this experimental study, we attempted to produce lung three-dimensional scaffold and assay its effect on cell penetration and migration. ...

Objective(s): Tissue engineering aims to achieve a tissue, which has highly interconnected porous microstructure concurrent with appropriate mechanical and biological properties. Materials and Methods: Therefore, the microstructure scaffolds are of great importance in this field. In the present study, an electroconductive poly-lactic acid (EC-PLA) filament used to fabricate a porous bone ...

Vascularization is a key issue for the success of tissue engineering to repair damaged tissue. In this study, we report a composite scaffold delivering angiogenic factor for this purpose. Vascular endothelial growth factor (VEGF) was loaded on mesoporous silica nanoparticle (MSN), which was then incorporated within a type I collagen sponge, to produce collagen/MSN/VEGF (CMV) scaffold. The CMV c...

heart failure is one of the leading causes of death worldwide. end stage disease often requires heart transplantation, which is hampered by donor organ shortage. tissue engineering represents a promising alternative approach for cardiac repair. for the generation of artificial heart muscle tissue several cell types, scaffold materials and bioreactor designs are under investigation. in this revi...

An elastomeric scaffold containing poly(glycerol sebacate) and hydroxypropyl-?-cyclodextrin was developed for soft tissue engineering.

objective: in this study we introduced an rgd-containing peptide of collagen iv origin that possesses potent cell adhesion and proliferation properties. this peptide was immobilized on a nanofibrous polycaprolactone/gelatin scaffold after which we analyzed human bone marrow-derived mesenchymal stem cells (hbmscs) adhesion and proliferation on this peptide-modified scaffold. methods: nanofibrous...

In bone tissue engineering, the organo-ceramic composite, electrospun polycaprolactone/hydroxyapatite (PCL/HA) scaffold has the potential to support cell proliferation, migration, differentiation, and homeostasis. Here, we report the effect of PCL/HA scaffold in tissue regeneration using human mesenchymal stem cells (hMSCs). We characterized the scaffold by fourier transform infrared spectrosco...

Introduction: Failure of human body tissue and organs is believed to be one of the most important health problems all over the world. The great challenge for tissue engineers is to optimize suitable systems to separate, proliferate and differentiate the cells so that they can set out to create tissue by a harmonic 3-D growth. Therefore, the tissue engineers must provide an environment like the ...

Tissue scaffolds provide a framework for living tissue regeneration. However, traditional tissue scaffolds are exogenous, composed of metals, ceramics, polymers, and animal tissues, and have a defined biocompatibility and application. This study presents a new method for obtaining a tissue scaffold from blood albumin, the major protein in mammalian blood. Human, bovine, and porcine albumin was ...
