BACKGROUND Severe graft-versus-host disease (GVHD) is a life-threatening complication after allogeneic transplantation with haemopoietic stem cells. Mesenchymal stem cells modulate immune responses in vitro and in vivo. We aimed to assess whether mesenchymal stem cells could ameliorate GVHD after haemopoietic-stem-cell transplantation. METHODS Patients with steroid-resistant, severe, acute GV...

Background: Mesenchymal stem cells are non-hematopoietic stromal cells that are used in the treatment of many chronic and autoimmune diseases by modulating the immune system. Due to the limitations of using autologous mesenchymal stem cells, the use of allogeneic stem cells is a promising therapeutic approach in the treatment of immunological disorders. This study aimed to investigate the abili...

liver failure, in an acute or chronic form, is a growing health problem ranking as one of the leading causes of death worldwide. inborn errors of metabolism characterized by defects in hepatic enzymes or other proteins with metabolic functions, such as receptors or transporters accompanied with environmental factors involve etiology and presentation of liver failure. currently, the only establi...

this study discusses the effect of complexes of chitosan grafted polyethylenimine(ch-pei) with plasmid dna on viability of mesenchymal stem cells(mscs) derived from human marrow. ch-pei/pdna nanoparticles were synthesized through the complex coacervation method using pires plasmid containing green fluorescent protein (gfp) gene. to confirm the complexation, samples were run through an agarose g...

conclusions our results suggested that cb-nk cells progenitors could proliferate and differentiate on feeder layer of amnion membrane mscs in combination with specific cytokines to produce nk cells for immunotherapy. results combination of cytokines and msc layer yielded significant fold expansion in comparison with cytokines without feeder conditions (day 7: 5.2 ± 1.12 and 2 ± 0.78, respective...

Tissue and cell transplantation are regarded as a popular procedure in clinical sciences, prospecting a new horizon for several incurable diseases. Along with its usefulness, many ethical concerns accompany this development. The ethical issue of organ transplant is unique to the source used which includes: living related, living unrelated, cadaveric, and xenotransplant. Obtaining organs has a s...

heart failure is one of the leading causes of death worldwide. end stage disease often requires heart transplantation, which is hampered by donor organ shortage. tissue engineering represents a promising alternative approach for cardiac repair. for the generation of artificial heart muscle tissue several cell types, scaffold materials and bioreactor designs are under investigation. in this revi...

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 the mo...
