Objective(s): Existing studies have demonstrated that intravenous and intramyocardial-administrated mesenchymal stem cells (MSCs) lead to tissue repair after cardiac disorders. We compared the efficiency of both administration methods.Materials and Methods: A rat model of isoproterenol-induced heart failure (ISO-HF) was established to co...

currently autografts are gold standards for craniomaxillofacial bone regeneration. but autografts have some limitations. bone tissue engineering has been introduced to overcome these limitations. it consist three components: stem cells, growth factor, and scaffold. scaffold provides an environment for bone growth and simplifies cell adhesion, differentiation and proliferation. in this review, a...

Tissue Engineering In article number 2207882, Ryan Y. Nguyen, Michael Mak, and co-workers report the fabrication of collagen I hydrogels with topology that mimics complex extracellular matrix architectures in tissues. The generated mesoscopic features, termed islands, are tunable modulate bulk hydrogel mechanical properties. Collagen islands can stem cell behavior differentiation. This method p...

objective(s)tissue engineering is an attractive science because it promises new therapeutic strategies for repairing organs that have lost functions due to damage. the purpose of this study was to evaluate induction effect of human gingival scaffold in tissue engineering for skin regeneration.materials and methodstissue samples were obtained from crown-lengthening procedures and wisdom teeth re...

stem cells are self-renewing cells that can be differentiated into other cell types. conventional in vitro models for studying stem cells differentiation are usually preformed in two-dimensional (2d) cultures. the design of three-dimensional (3d) in vitro models which ideally are supposed to mimic the in vivo stem cells microenvironment is potentially useful for inducing stem cell derived tissu...

Objective(s):Osteoarthritis (OA) is globally one of the most common diseases from the middle age onwards. Cartilage is an avascular tissue therefore it cannot be repaired in the body. Conservative treatments have failed as a good remedy and cell therapy as a decisive cure is needed. One of the best and easily accessible cell sources for this purpose is adipose-derived stem cells which can be di...

Multipotent mesenchymal stromal cells or mesenchymal stem cells (MSCs) are mainly isolated from bone marrow or fat tissue. Because of their potential of multilineage differentiation towards bone, cartilage and fat tissue, they were initially evaluated to develop innovative strategies for tissue engineering applications. More recently, they have gained interest based on their immunomodulatory pr...

Bone marrow-derived mesenchymal stem cells (BMSCs) have been extensively studied for potential clinical use. Recently, increasing attention is being paid to the relationship between p53 and BMSCs differentiation. In this study, we investigated effects of on alveolar epithelial differentiation BMSCs. Rat (rBMSCs) were cultured with without hyperoxia-damaged lung tissue observe their process in v...

Background  Isolation of adipose tissue mesenchymal stem cells (MSCs) with current enzymatic methods has some limitations. For example, it is costly and time-consuming and results in a heterogeneous cell population that making compromise proliferation and differentiation of MSCs. Also, it is accompanied with the increased risk of culture contaminations because of several handling steps.In this...

Objective(s): Design and construction of biocompatible and biodegradable scaffolds are among the main goals of tissue engineering. Recently, use of nano-hydroxyapatite as a bioactive bioceramic agent with high similarity to the mineral phase of the human bone tissue, in combination with biodegradable polymers and implant coatings has attracted the attention of researchers in the field of biomat...
