background :delayed ::::union::::, non::::union::::, and mechanical failure is still problems encountered in limb salvage surgery (lss) using extracorporeal irradiation (eci). this study aimed to determine whether bone marrow mesenchymal stem cells (msc) and recombinant human bone morphogenetic protein-2 (rhbmp-2) improve host-graft ::::union:::: after osteotomy and also increase its mechanical...
introduction: as an inherited neurodegenerative disease, huntington's disease is accompanied with wide neuronal degeneration in neostriatum and neocortex. progress of the disease causes disabling clinical effects on movements, recognition and physiology of the body, and finally results in death. at this stage of knowledge we are, there is no effective therapeutic strategy for diminishing t...
abstractbackground: fetal bovine serum (fbs) is widely used in cell culture laboratories,risk of zoonotic infections and allergic side effects create obstacles for its use inclinical trials. therefore, an alternative supplement with proper inherent growthpromotingactivities is demanded.objective: to find fbs substitute, we tested human umbilical cord blood serum(hucs) for proliferation of human...
The bone marrow microenvironment comprises multiple cell niches derived from bone marrow mesenchymal stem cells. However, the molecular mechanism of bone marrow mesenchymal stem cell differentiation is poorly understood. The transcription factor GATA2 is indispensable for hematopoietic stem cell function as well as other hematopoietic lineages, suggesting that it may maintain bone marrow mesenc...
Objective- Investigate myocardial performance after autologous adipose-derived (ASCs) mesenchymal stem cell differentiated under equiaxial cyclic strain, transplantation in rabbits with acute myocardial infarction (AMI). Design- Prospective, randomized experimental study Animals- 20 New Zealand White rabbits (2-3 kg) P...
objective articular cartilage as an avascular skeletal tissue possesses limited capacity to heal. on the other hand, it is believed that the regeneration capacity of each tissue is largely related to its stem cell contents. little is known about the presence of mesenchymal stem cells in articular cartilage tissue. this subject is investigated in the present study. materials and methods articula...
Background and Objectives: Control processes in osteoblastic differentiation of mesenchymal stem cells are not yet fully understood. Epigenetic mechanisms, especially the methylation of CpG Islands in the promoter of genes, are considered as one of the most important control mechanisms in stem cell differentiation. In the process of differentiation, it is debated whether only the methylation of...
STUDY DESIGN Posterolateral lumbar transverse process fusion was carried out using cultured mesenchymal stem cells with or without bone morphogenetic protein (BMP) and basic fibroblast growth factor (FGF). OBJECTIVES To determine the ability of BMP and basic FGF to enhance the efficacy of bone marrow-derived mesenchymal stem cells in lumbar arthrodesis. SUMMARY OF BACKGROUND DATA Our previo...
Modified mesenchymal stromal cells (MSCs) display a unique mechanism of action during the repair phase of traumatic brain injury by exhibiting the ability to build a biobridge between the neurogenic niche and the site of injury. Immunohistochemistry and laser capture assay have visualized this biobridge in the area between the neurogenic subventricular zone and the injured cortex. This biobridg...
Background: It is still controversial that the stem cells isolated from human dental pulp meets the criteria for mesenchymal stem cells (MSCs). The aim of the present study was to examine whether or not they are MSCs, or are distinct stem cells population residing in tooth pulp. Methods: Adherent fibroblastic cells in the culture of pulp tissue from human third molars were propagated through se...
