Medicinal chemists have traditionally realized assessments of chemical diversity and subsequent compound acquisition, although a recent study suggests that experts are usually inconsistent in reviewing large data sets. To analyze the scaffold diversity of commercially available screening collections, we have developed a general workflow aimed at (1) identifying druglike compounds, (2) clusterin...

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 ...

Scaffolds for regenerative medicine applications should instruct cells with the appropriate signals, including biophysical stimuli such as stress and strain, to form the desired tissue. Apart from that, scaffolds, especially for load-bearing applications, should be capable of providing mechanical stability. Since both scaffold strength and stress-strain distributions throughout the scaffold dep...

INTRODUCTION Low back pain is a major economical and social problem nowadays. Intervertebral disc herniation and central degeneration of disc are two major reasons of low back pain that occur because of structural impairment of disc. The intervertebral disc contains three parts as follows : Annulus fibrosus, transitional region, and nucleus pulposus, which forms the central nucleus of the disc....

Tissue engineering scaffold is a biological substitute that aims to restore, to maintain, or to improve tissue functions. Currently available manufacturing technology, that is, additive manufacturing is essentially applied to fabricate the scaffold according to the predefined computer aided design (CAD) model. To develop scaffold CAD libraries, the polyhedrons could be used in the scaffold libr...

Introduction: The native inability of nervous system to regenerate, encourage researchers to consider neural tissue engineering as a potential treatment for spinal cord injuries. Considering the suitable characteristics of induced pluripotent stem cells (iPSCs) for tissue regeneration applications, in this study we investigated the adhesion, viability and proliferation of neural progenitors (de...

In this present study, we examined the differentiation potential of human bone marrow derived mesenchymal stem cells (hBMSCs) into hepatocytes on a three-dimentional (3D) nanofibrous scaffold formed by Poly (ε-caprolactone) (PCL), collagen and polyethersulfone (PES). The nanofiber was prepared by the electrospining technique. HBMSCs were isolated using combining gradient density centrifugation ...

background :delayed ::::union::::, non::::union::::, and mechanical failure is still problems encountered in limb salvage surgery (lss) using extracorporeal irradiation (eci). this study aimed to determine whether bone marrow mesenchymal stem cells (msc) and recombinant human bone morphogenetic protein-2 (rhbmp-2) improve host-graft ::::union:::: after osteotomy and also increase its mechanical...
