Background and Aim: Adipose-derived stem cells (ADSCs) represent a promising source of cells for cardiac tissue engineering and repair of the injured heart. However, better understanding of the factors affecting the cardiac differentiation of ADSCs is required before clinical application of these cells. Current study was designed to investigate the role of bFGF and BMP4 in cardiac differentiati...
Anisotropic silk biomaterials containing cardiac extracellular matrix for cardiac tissue engineering
Abstract This work introduces the novel gelatin/chitosan blend scaffolds containing different amounts of functionalized multi-walled carbon nanotubes (f-MWCNTs) up to 0.1wt%, which were prepared by freeze drying (freezing and lyophilization). The composite scaffolds were characterized by Fourier transformed infrared spectroscopy (FTIR) to distinguish the functional groups and different bonds in...
Objective(s):Cardiomyocytes have small potentials for renovation and proliferation in adult life. The most challenging goal in the field of cardiovascular tissue engineering is the creation of an engineered heart muscle. Tissue engineering with a combination of stem cells and nanofibrous scaffolds has attracted interest with regard to Cardiomyocyte creation applications. Human adipose-derived s...
Background: In spite of promising results of conventional treatments for myocardial infarction, including medications, stent implantation, and coronary artery bypass grafting, the disease and its complications, especially heart failure, are highly prevalent because these methods could not reverse the cell loss, which is the main problem. Currently, heart transplantation, as the last option f...
The role of heart disease in increasing worldwide death and the limited availability of organs for transplantation have encouraged multiple strategies to fabricate functional and implantable constructs. One of these strategies is to develop a biologically similar heart tissue scaffold, in which two types of fiber and hydrogel are commonly used. Toward this goal, taking advantage of both hydroge...

In vitro application of pulsatile electrical stimulation to neonatal rat cardiomyocytes cultured on polymer scaffolds has been shown to improve the functional assembly of cells into contractile engineered cardiac tissues. However, to date, the conditions of electrical stimulation have not been optimized. We have systematically varied the electrode material, amplitude and frequency of stimulatio...
objective (s): the scarcity of articular cartilage defect to repair due to absence of blood vessels and tissue engineering is one of the promising approaches for cartilage regeneration. the objective of this study was to prepare an extracellular matrix derived decellularized bovine articular cartilage scaffold and investigate its interactions with seeded rat bone marrow mesenchymal stem cells (...
