Background: Increasing number of patients facing end-organ failure, as well as the therapeutic challenges surrounding allotransplantation, has catalyzed the evolution of tissue engineering and regenerative medicine. The successful recapitulation of development requires choosing an ideal scaffold material as a mediator of biochemical and biophysical signals. The extracellular matrix (ECM) functi...

Background: In the present study, a tissue engineered silk fibroin (SF) scaffold containing simvastatin-loaded silk fibroin nanoparticles (SFNPs) were used to stimulate the regeneration of the defected bone. Methods: At first, the porous SF scaffold was prepared using freeze-drying. Then simvastatin-loaded SFNPs were made by dissolvation method and embedded in the SF scaffold. Afterwards, the ...

Background and Objective: Tissue engineering is a new method for replacing damaged tissue components in order to improve its function. In this method, a porous scaffold mixed with polysaccharide and synthetic antioxidants is first produced and then stem cells are cultured inside it. In this study, the polycaprolactane-chitosan-tannic acid scaffold was used to reproduce the amount Fibroblast cel...

    Background & Aims: Nerve tissue engineering (NTE) is one of the most promising methods for the treatment of the central nervous system (CNS) neurodegenerative diseases. The three-dimensional distribution and growth of the cells within the porous of the scaffold have a significance clinical role in the NTE field. Scaffolds used in tissue engineering, not only must have a good performance, bu...
