objective: the present study examines the effects of increased heat shock proteins expression in mda-mb468 adeno-carcinoma cells on expansion and differentiation of hematopoetic stem cells from human umbilical cord blood. materials and methods: highly purified human cd34+ cells (magnetic bead isolation) derived from umbilical cord blood were cultured, under three conditions, in the presence of ...
brain injuries that caused by strokes (result of intra partum ischemia) are a frequent cause of prenatal mortality and morbidity with limited therapeutic options. transplanting human mesenchymal stem cells (hmscs) indicates improvement in hypoxic ischemic brain injury (hibd) by secretion growth factor stimulating repair processes (hmscs) known as multi potent cells which isolated from bone marr...
background: mesenchymal stromal cells (mscs) are employed in various different clinical settings in order to modulate immune response. human autologous and allogeneic supplements including platelet derivatives such as platelet lysate (pl), platelet-released factors (prf) and serum are assessed in clinical studies to replace fetal bovine serum (fbs). the immunosuppressive activity and multi-pote...
umbilical cord blood (ucb) has been used for transplantation in the treatment of hematologic disorders as a source of hematopoietic stem cells (hscs). because of insufficient number of cord blood cd34+ cells, the expansion of these cells seems to be important for clinical application. mesenchymal stromal cells (mscs), playing an important role in hscs maintenance, were used as feeder layer. apo...
Many investigators have used xenogeneic, especially murine stromal cells and fetal calf serum to maintain and expand human stem cells. The proliferation and expansion of human hematopoietic stem cells in ex vivo culture were examined with the goal of generating a suitable protocol for expanding hematopoietic stem cells for patient transplantation. Using primary fetal liver cells, we established...
background: atherosclerosis, a chronic inflammatory disease of the vessel wall is characterized by local and systemic immune responses to a variety of antigens. oxidized low-density lipoprotein (oxldl) is considered as an important determining factor in the pathogenesis of atherosclerosis. objective: the purpose of this study was to investigate the degree of peripheral blood mononuclear cells (...
