Background Degenerative retinal diseases, including age related macular degeneration, glaucoma, and hereditary retinal dystrophies are major causes of blindness. The principal defect in these diseases is cell loss which is amenable to both cell based neuroprotective and neuroregenerative therapies. To briefly review the lines of research and potential candidates for cell based therapies among ...

BACKGROUND We previously found in a murine hematopoietic system that hematopoietic stem cells show high differentiation and proliferation capacity on bone marrow-derived mesenchymal stem cells/stromal cells (microenvironment) with "self" major histocompatibility complex (MHC). DESIGN AND METHODS We examined whether amnion-derived adherent cells have the characteristics of mesenchymal stem cel...

a neurological disorder is any disorder of the nervous system is usually due to cell loss. the ultimate goal of cns therapy is to replace lost cells and tissue. there is no neuroprotective, pharmacological and effective treatment available that restores the injury-induced loss of function. recent studies suggest that identification of adult neural stem/progenitor cells indwelling in the neuroge...

OBJECTIVE To evaluate the effect of low-level laser irradiation on the proliferation and possible nuclear morphological changes of mouse mesenchymal stem cells. METHODS Mesenchymal stem cells derived from bone marrow and adipose tissue were submitted to two applications (T0 and T48 hours) of low-level laser irradiation (660 nm; doses of 0.5 and 1.0 J/cm2). The trypan blue assay was used to ev...

Background and Aims: Cartilage is a very specific tissue, which does not have the capacity to heal and renew itself. Although the invention of the method of surgery with autologous chondrocyte transplantation, developed tools to treat the cartilage lesions, it couldn’t gain a great success due to problems such as damage to the area of donation. Using the mesenchymal stem cells derived from adip...

osteoarthritis (oa) is a prevalent chronic disease impacting on quality of life and has societal and economical burden increasing with age. yet, no confirmed pharmacological, biological or surgical therapy could prevent the progressive destruction of oa joint. mesenchymal stem cells (mscs) with immunosuppressive activities emerged a potential therapy. we describe a magnetic resonance images (mr...

traffic accident has increased in the last decade. one of the most important outcomes of accident is spinal cord injury (sci). so, cell therapy is obtained a greater attention in most fields of medicine because of its potential for incurable diseases through replacing of dead cells. the current study aims to describe the important of locomotor functional and structural connection of the spinal ...

background: myocardial infarction is the main cause of death worldwide. angiogenesis, a promising new therapy for the treatment of diffuse coronary artery disease, shows a poor response to conventional revascularization techniques. this study focused on improving myocardial function using endothelial cells (ecs) and mesenchymal stem cells (mscs) in a sheep animal model. methods: acute myocardia...

introduction: iiron oxide nanoparticles (io np) have an increasing number of biomedical applications. to date, the potential cytotoxicity of these particles remains an issue of debate. little is known about the cellular interaction or toxic effects of io np on differentiation of stem cells. the aim of the present study was to investigate the possible toxic role of different doses of io np in di...

objective(s): umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine.  the objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. materials and ...
