this investigation aimed to examine the protective function of vitamin e on rat bone marrow mesenchymal stem cells (mscs) treated with cadmium chloride. rat bone marrow mscs were extracted using flashing-out and cultured in dmem containing 10% fbs and 100 u/ml pen/strep. at the end of the third passage, cells were divided into 4 groups including control, cadmium chloride, cadmium chloride + vit...

the wharton’s jelly of the umbilical cord is believed to be a source of mesenchymal stem cells (mscs) which can be therapeutically applied in degenerative diseases. in this study, we investigated the immunomodulatory effect of umbilical cord derived- mesenchymal stem  cells (uc-mscs) and  bone  marrow-derived-mesenchymal stem  cells (bm-mscs) on differentiation, maturation, and endocytosis of m...

introdution: stroke is one of the most common diseases caused by occlusion or rupture of blood vessels in brain. it brings heavily loads for families and societies. although some new strategies including treatment of tissue plasminogen activator have been applied in the clinic, these methods do not have perfect effect. accordingly, more effective therapeutic strategies need to be developed. thi...

Graft versus host disease (GVHD) following liver transplant occurs in 0.1-2% of patients and portends a poor prognosis. Affected organs include skin, the gastrointestinal tract and bone marrow. We present the case of a 61 year old female who developed skin rash and pancytopenia following sex-mismatched second liver transplant for autoimmune hepatitis. Initial skin biopsies revealed vacuolar int...

OBJECTIVES Stem cell therapy may be useful in chronic myocardial infarction (MI); this is conceivable, but not yet demonstrated in humans. BACKGROUND After acute MI, bone marrow-derived cells improve cardiac function. METHODS We treated 18 consecutive patients with chronic MI (5 months to 8.5 years old) by the intracoronary transplantation of autologous bone marrow mononuclear cells and compare...

The study was designed to evaluate reactive oxygen species (ROS)/nitric oxide (NO) formation and apoptotic/necrotic cell death elicited by prednisolone in peripheral blood and bone marrow mononuclear cells and to define the efficacy of vitamin D3 to counter glucocorticoid (GC)-induced changes. It was shown that prednisolone (5 mg per kg of female Wistar rat’s body weight for 30 days) evoked ROS...

Introduction: Hematopoiesis is an on going process mammalian marrow system. A few cells from the nucleated cells of bone marrow are hematopoietic cells which include primary stem cells, precursor cells and progenitor cells. Primary stem cells and progenitor cells are able to produce colonies in culture medium (CFU-C) and irradiated mouse spleen (CFU-S). A hematopoietic cell is alive and act...

Cytomegalovirus latency depends on an interaction with hematopoietic cells in bone marrow and peripheral blood. The distribution of viral DNA was investigated by PCR-driven in situ hybridization (PCR-ISH), and the number of viral genomes per cell was estimated by quantitative competitive PCR during both experimental and natural latent infection. During experimental latent infection of cultured ...
