rabbits have the capacity to regenerate holes in their ears by forming a blastema, a tissue that is made up of a group of undifferentiated cells. the purpose of the present study was to isolate and characterize blastema progenitor cells and compare them with marrow mesenchymal stem cells (mscs). five new zealand white male rabbits were used in the present study. a 2-mm hole was created in the a...

There is currently great interest in the use of mesenchymal stem cells as a therapy for multiple sclerosis with potential to both ameliorate inflammatory processes as well as improve regeneration and repair. Although most clinical studies have used autologous bone marrow-derived mesenchymal stem cells, other sources such as allogeneic umbilical cord-derived cells may provide a more accessible a...

Introduction: Mesenchymal stem cells can be isolated from adult tissues, such as the adipose tissue, or other sources. Among all these sources, adipose tissue because of easy access, and placenta due to its immunomodulatory properties, in addition to another useful properties, were attracted more attention to themselves. Isolation and comparing these two different sources can help us for acces...

background: perioglasâ (pg) is an alloplastic material used for grafting periodontal osseous defects since 1995. in animal models, it has been proven that pg achieves histologically good repair of surgically created defects. in clinical trials, pg was effective as an adjunct to conventional surgery in the treatment of intrabony defects. because the molecular events due to pg that are able to al...

up-regulation of cd4+cd25+cd127low/- regulatory t cells (tregs) is a new target in the treatment of asthma. human bone marrow mesenchymal stem cells can up-regulate cd4+cd25+cd127low/- regulatory t cells in vitro,  meanwhile, heme oxygenase-1 (ho-1) plays an important role in the development and maintenance of cd4+cd25+ regulatory t cells. however the mechanism has not yet been adequately under...

Glial cell line-derived neurotrophic factor recombinant adenovirus vector-transfected bone marrow mesenchymal stem cells were induced to differentiate into neuron-like cells using inductive medium containing retinoic acid and epidermal growth factor. Cell viability, microtubule-associated protein 2-positive cell ratio, and the expression levels of glial cell line-derived neurotrophic factor, ne...

Background Mesenchyme stem cells (MSCs) are one of the widely used sources in tissue engineering and efficacy of cultural environment. In this survey, rat stem cells are used as coculture. Owing to main obstacle of embryo culture in the lab medium, the survival of embryo in lab is low in comparison with that of normal conditions. The purpose of this research is the survey of fertilization and c...
