tissue engineering based on the adipose derived stem cells promote a strong strategy to propagation of bone, cartilage and fat tissues in the three-dimensional scaffolds, fabricated by combining biological materials with suitable and appropriate growth factors. in this study, a peo scaffold was used to show that mesenchymal stem cells can attach well; the aim of this study was the investigati...
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...
Background and purpose: Studies showed that biocompatible and biodegradable materials in tissue engineering can be used to heal wounds. The aim of this study was to fabricate polyurethane/royal jelly/hyaluronic acid scaffold with suitable biological properties for wound healing using electrospinning method. Materials and methods: In this applied experimental study, to make a nanofiber scaffold...
in this study, based on a biomimetic approach, novel 3d biodegradable porous hybrid scaffolds consisting of chitosan, gelatin, and tricalcium phosphate were developed for bone and cartilage tissue engineering. macroporous chitosan/ gelatin/β-tcp scaffolds were prepared through the process of freeze-gelation/solid-liquid phase separation. the results showed that the prepared scaffolds are highly...
Background: Stem cells represent an ideal cell source for application in tissue engineering and regenerative medicine due to their ability to proliferate and differentiate to a wide variety of cell lineages. With recent development of medical sciences and tissue engineering, usage of adipose-derived mesenchymal stem cells, their culture and differentiation on suitable scaffolds are considered a...
objective: the incidence of heart valve disease is increasing worldwide and the number of heart valve replacements is expected to increase in the future. by mimicking the main tissue structures and properties of heart valve, tissue engineering offers new options for the replacements. applying an appropriate scaffold in fabricating tissue-engineered heart valves (tehvs) is of importance since it...
Background & Aim: The use of bone scaffolds is one of the new and efficient techniques for repairing bone defects that provide a suitable platform for cell proliferation and growth to repair the target tissue. One of the most important causes of failure of transplants and surgical procedures is the invasion of bacteria at the site of the complication and the development of severe infection. The...
Introduction: Poly lactic co- glycolic acid (PLGA) and poly caprolacton (PCL) are highly applicable polymers in the field of drug delivery and tissue engineering scaffolds. Therefore, this study aimed to design an insulin-loaded PCL/PLGA hybrid nanofiber scaffold in order to be applied in attachment and growth of chondrocytes. Moreover, it can provide a vehicle for the controlled release of a...
objective: we studied both the presence of some carbohydrate compounds in a three-dimensional (3d) matrix harvested from human gingiva and the cell behavior in this matrix. materials and methods: in this experimental research, in order to prepare 3d scaffolds, human palatal gingival biopsies were harvested and physically decellularized by freeze-thawing and sodium dodecyl sulfate (sds). the sca...
Suitable alternatives are made for damaged or diseased organs and tissues in tissue engineering by combining cellular and molecular biology with materials and mechanical engineering. Fibrin is a critical blood component responsible for homeostasis, used extensively as a biopolymer scaffold in tissue engineering. This study summarizes the latest developments in organ and tissue regeneration usin...
