Background and Objective: Differentiation of mesenchymal stem cells into neurons has great potential in the therapy of damaged nerve tissue. Neural tissue engineering offers tremendous promise to combat the effects of disease, aging and injury in the nervous system. The aim of this study was to investigate the differentiation of adipose derived stem cells to neuron like cells on aligned nanofib...
background: hemophilia b is an x-linked hereditary disorder of blood coagulation system which is caused by factor ix (fix) deficiency. factor ix is a plasma glycoprotein that participates in the coagulation process leading to the generation of fibrin. replacement of factor ix with plasma-derived or recombinant factor ix is the conventional treatment for hemophilia b to raise the factor ix level...
background the aim of this clinical trial was the assessment of safety and efficacy of submocosal and periurethral injections of peripheral blood derived autologous stem cells along with platelets, and focused on outcome for six months. methods an open, prospective study was conducted on 10 patients presenting with stress urinary incontinence. at the baseline (pre-operative), 1, 3 and 6 months ...
Background and Objective: Specific differentiation processes to various cell lineages are closely associated with factors such as transcription factors, tumor suppressor elements and internal signaling pathways including vHL, Ecad, and Runx3. Epigenetics is an effective control mechanism of these factors, including several mechanisms such as methylation and acetylation. The main objective of th...
Purpose: Effects of TGF-b and b-FGF on the Potential of Peripheral Blood-Borne Stem Cells and Bone Marrow-Derived Stem Cells In Wound Healing in a Murine Model.Materials and Methods: Peripheral blood mesenchymal stem cells (PBMSCs) and bone marrow stem cells (BMSCs) cultured in media with transforming growth factor-beta (TGF-b) and basic fibroblast growth factor (b-FGF). Stem cells labeled with...
Background and purpose: Articular cartilage disease is prevalent in all societies and in most cases the damaged cartilage would not repair. Conservative treatments are associated with many problems. So cell therapy is needed as a definite treatment. One of the best and most accessible sources of cells for this purpose is stem cells derived from adipose tissue which can be differentiated into ch...
Background and purpose: Today, increased rate of demand for insulin is predictable due to increasing cases of diabetics in the world. Therefore, it is necessary to develop economic approaches and increasing the production of insulin for the future and medicinal plants could be regarded as a promising prospect for insulin production. Materials and methods: The Allium ursinum and Silybum marianu...
Background Chronic allograft nephropathy(CAN) is one of the most common causes of chronic and end stage renal disease. It is defined with Mainly tubular atrophy and interstitial fibrosis and no evidence of any other etiology, or functional disorder that caused at least three months after transplantation . Control of risk factors (HTN,DM,HLP, …) and limiting usage of calcineurin inhibitors...
Background Infertility affects around 15% of couples, and male factors account for 50%. Cryptorchidism is one of the most common causes for azoospermia. Generation of functional spermatids from azoospermia patients is of unusual significance for treating male infertility. It has been recently reported by peers and us that human spermatogonial stem cells (SSCs) can be clearly identified and cult...
Objective: In this study, the bone regeneration ability of polyacrylamide hydrogel and nanohydroxyapatite scaffolds (PAAH/NHA) and stem cells derived from adipose tissue (ADSCs) in the healing of critical sized bone defects in rabbit radius were assessed. Animals and procedures: 12 New Zealand white male rabbits were divided into 3 groups. The rabbits were anesthetized and 15 mm bone def...
