Objectives- To isolate, culture-expand and differentiate mesenchymal stem cells from ovine bone marrow and determine their culture requirements for high expansion rate. Design- Experimental study. Animals- Five Shal sheep. Procedures- In this study, ovine marrow cells were plated and culture expanded through 3 successive subcultures. The resultant cells were then plated at differentiating condi...

objective(s):to study the effect of low-frequency vibration on bone marrow stromal cell differentiation and potential bone repair in vivo. materials and methods:forty new zealand rabbits were randomly divided into five groups with eight rabbits in each group. for each group, bone defects were generated in the left humerus of four rabbits, and in the right humerus of the other four rabbits. to t...

Background:  Renal transplantation is the best choose in the end stage renal disease (ESRD), and acute rejection and graft dysfunction remain major challenges in the worldwide, even with the advent of new immunosuppressive drugs. The novel cell-based anti-rejection treatments have been studied by using different stem cell sources. In this study, transplantation of autologous-bone-marrow-derive...

Background: Acute myeloid leukemia (AML) is characterized by the proliferation of myeloid precursors and abnormal differentiation of hematopoietic stem cells, which results in the accumulation of immature cells in the bone marrow (BM). The accumulation of these cells in the bone marrow causes molecular and cellular changes in the microenvironment of the bone marrow. The adiponectin hormone orig...

  Background and Objectives: Bone marrow necrosis (BMN) is a rare and ominous complication of wide variety of diseases including hematologic malignancy. This study was performed to identify frequency and the underlying associated diseases of marrow necrosis. Materials and Methods: In this descriptive study, totally 850 bone marrow trephine biopsies related to living patients at the Pathology ...

objective(s):immunosuppressive property of mesenchymal stem cells (mscs) has great attraction in regenerative medicine especially when dealing with tissue damage involving immune reactions. the most attractive tissue sources of human mscs used in clinical applications are bone marrow (bm), adipose tissue (at), and wharton's jelly (wj) of human umbilical cord. the current study has compared...

background: cell therapy of many neurodegenerative diseases using bone marrow stromal cells (bmsc) requires the differentiation of bmsc into neuronal subtype. however, the transdifferentiation of bmsc into gabaergic phenotype requires more investigation. methods: in this study, bmsc of adult female rats were pre-induced into neuroblast-like cells using 1 mm β-mercaptoethanol (βme) and 10 m ret...
