BACKGROUND: Bone marrow-derived mesenchymal cellscan transdifferentiate into Cardiomyocyte cells and improveheart function after transplantation. Since biomaterials canimprove the cell retention in the site, cell survival and differentiation,heart tissue engineering is now being explored as anapplied solution to support cell-based therapies and increasetheir efficacy for myocardial diseases. Ch...

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 ...

We prepared a bone scaffold material comprising a PLGA/β-TCP core and a Type I collagen cladding, and recombined it with bone marrow stroma stem cells (BMSCs) to evaluate its potential for use in bone tissue engineering by in vivo and in vitro experiments. PLGA/β-TCP without a cladding was used for comparison. The adherence rate of the BMSCs to the scaffold was determined by cell counting. Cell...

Background: engineering new bone tissue with cells and a synthetic extracellular matrix represents a new approach for the regeneration of mineralized tissues compared with the transplantation of bone (autografts or allografts). Methods: in this study, to mimic the mineral and organic component of natural bone, hydroxapatite (HA) and gelatin (GEL) composite scaffolds were prepared. The raw mater...

Background and purpose: Adipose - drived stem cells are multipotent cells that capable to diffrentiate in to osteogenic cells. On the other hand, the scaffold of chitosan and gelatin are biodegradable and compatible used for tissue repair. This study evaluated the repair of femoral bone defect using adipose-derived stem cells on gelatin – chitosan membrane in adult Albino Wistar rats by radiog...

Bone tissue engineering scaffolds should be designed to optimize mass transport, cell migration, and mechanical integrity to facilitate and enhance new bone growth. Although many scaffold parameters could be modified to fulfill these requirements, pore size is an important scaffold characteristic that can be rigorously controlled with indirect solid freeform fabrication. We explored the effect ...

Scaffold fabrication and biocompatibility are crucial for successful bone tissue engineering. Nanometer hydroxyapatite (nHAP) combined with collagen (COL) is frequently utilized as a suitable osseous scaffold material. Furthermore, growth factors, including bone morphogenetic protein‑2 (BMP‑2), are used to enhance the scaffold properties. The present study used blending and freeze‑drying method...

In this study, mechanical properties and apatite formation ability of synthesized fluorapatite-hardystonite (FA-HT) nanocomposite scaffolds were investigated. Hardystonite (HT; 5 and 10 wt.%) as a reinforcement phase was incorporated into the FA scaffold. FA was mixed with HT for 4 h under argon gas at 220 °C. A space holder method was used for fabricating porous FA-HT scaffolds. Sodium chlorid...
